Simplified quotation / contract system via web.

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 "NAME" "CUSTOMER" 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'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 "contract signed" 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.
