    I need someone to take my basic service agreement, and then add options to fill in the blanks, so that I can quickly create contracts/agreements to send to customers. I would like to access it from an internal web server where all the files will be saved, and searchable. When I enter a contact details once, it should always stay in the system, so that I can select their name from the drop down list, and it should automatically propagate the proper areas in the agreement, like, name,address,phone, etc... I will provide you with a sample agreement with tags like &quot;NAME&quot; &quot;CUSTOMER&quot; etc... You will need to create one input form where I can input all the data quickly. There is a section that will need to be calculated as well. i.e first month, last month, and duration contract. So if the customer does a 36 month contract with me, then the app should automatically input the END date if I selected the START date. All of the files must keep a certain code, that is generated from items within the input section, for example, Location A name, Location B name, customer name, date... That should be the file name. All of the files should be searchable from the portal. Any changes or modifications to a agreement, will add the -1 or -2 to the end of the file name so that its known that this is the 2, or 3rd version of the agreement. The portal should have a calendar bases scroll section where I can monitor start and end dates of my clients. I need to have a notification system that will alert me X months, X weeks before a customer&quot;s contract expires. I would also like to track future customer as well. Sometimes I need to wait months before I can bid on a contract again. That should be in my calendar with the details of that client, and in a different colour. I want to have notifications for all of this, sent weekly, monthly etc... There must be an option to export contact emails and or addresses so that I can print labels or what ever else is needed.For bonus options..... If you are a quickbooks expert, I would like you to integrate this with my quick books so that once make a contract, and in the portal there can be a option for &quot;contract signed&quot; it should automaticly send the details to quickbooks and generate the invoices, as well as build the customer into the quickbooks database.Sorry for the long ramble, but those with experiance in this, will know exactly what I need.

We need an example web application built for us that will have a logon page and then a main screen with a left hand navigation bar, top menu bar and main screen in the middle.We need to hook in all the different screens into the menu and navigation bar (about 20 screens will need to be setup) but we only need to have one screen to be functional and we can then complete the rest. The functional screen will have a simple data entry screen that can be added/updated and on entry will show the contains from the database. As navigation and menu options are selected the middle area will be refreshed with the new screen.We want to use Java, Spring, MVC, Hibernate, Maven, Eclipse. We need a clean implementation so that we can build the rest of the project.

    I am looking for someone who can build me a Swing user interface that I can use to demonstrate the functionality of my simple project management application. My application (partially complete) allows individuals to plan software development projects. You could relate it to something like JIRA or RALLY but I must stress that it is much much simpler. The user interface I require should be able to construct some basic entity objects (I will provide these) from various screens. Some simple checks should be incorporated into the UI when constructing objects (e.g. project name is not empty). In terms of the screens, I have no mock designs so you can either create your own based on my requirements (something similar to JIRA would be ideal although it does not need to be as complex) or I can try to put together some mock designs. The two MOST IMPORTANT things I am looking for is someone who can do this quickly and someone who is reliable. This is an urgent task that I need completed on 20/04/14 so please do not bid if you don’t think you will have enough time or if you have too many other projects to deal with. I need to make sure this is DONE on the date specified. It is a simple task so it should not take long for someone who is familiar with Swing. Further information will be provided to the successful bidder but please do not hesitate to ask me questions if you are unsure of anything.

    I need a simple Android-Appengine application for my school project. The app will send a request to the appengine with user info and some data, then the appengine will do some calculation and reply with some stored information.The calculation part can be left empty for me to put my algorithm later. It can be like user choose 1,2,or 3, then the appengine reply with dataset-1, 2,or 3 from the datastore in JSON format. You can put some dummy data inside. The appengine needs to log all the user request, and allows me to download and update the stored information like in cvs format. The code should be properly commented, especially where to put the logic part.My logic will not be very complicated, it will be like the appengine looks at the user age, then retrieve the data that matches the age range. I will expand this part myself.No need android UI design.No need web interface.

    I am working on a project but don&quot;t really have spare time to complete. This is a full stack development. Requires 3 core components1) Server side:There will be more than 1 servers, servers will communicate with each other by using RabbitMQ either shovel or federation(as servers are not located in the same datacenter) (please don&quot;t offer me anything if you&quot;ve never worked on any AMQP, I don&quot;t like sockets or similar ways of &quot;missing implementations for the real world&quot;). The idea of having more than one server is reliability. Servers will have a database and all servers need to synchronize databases when there is an insert/update. Don&quot;t worry about the details of the database I would only require 3-4 simple tables. I&quot;d prefer SQLite for that as it is only a file and does not require any installation.The other part of server side is Android-Server communication, Android client should be able to get all available server addresses so that any disconnection must be handled by the other server (you don&quot;t have to worry about this part, simply if ack is not received you can have a pop up saying it is disconnected and expect user to do the task again). The client will log in into this server, and server will have database wrappers to be able to write/read data from database(clients will not directly connect to the database). This client-server communication will also be done by RabbitMQ, however must be separated from the server-server communication. The last part is HTTP server. The same username password used for Android client will be used to log in. This will be used for a browser client to view and edit the database.This server must be written in Java and all external libraries must be working fine with Linux and Windows. I have cross-compatiable libraries for SQLite and HTTP Server. I can send it if necessary.2) Android clientThe client will have 2 roles(determined by the account), therefore they will have different Activities. Again the role determination is done at the server side, nothing will be determined by the client. The client must be written for tablets, not for phones.3) HTTPAs mentioned above will be very basic, just log in screen and view/modify some database fields(determined by the account)Please contact me if you have questions or would like to learn more about it.

    This project involves creating a program that will monitor the prices of specific items within marketplaces/exchanges on a couple of different websites. The key objectives of this piece of software will be:1. Track the specific prices requested and send an email alert when the price reaches a pre-determined &quot;alert level&quot; which will be provided to you. 2. The program should be dynamic enough to be able to change that &quot;alert level&quot; on demand, as well as add or remove which items are being monitored. 3. The program should scan the marketplaces and check the prices 4 times a day: 12AM, 6AM, 12PM and 6PM central standard time (US).4. The software must be written in JavaScript, no exceptions. A successful outcome will be a clean, functioning piece of software that operates exactly to our specifications and whose parameters can be easily modified at any time.
