    I know you get this request all the time and I am in now way trying to low ball this project. I studied math and many of my peer in university studied computer science and I first hand know this is a huge project. But I also know the average going rates for software development so lets play fair ball pure business/service. I need to develop a website with a monthly registration fee as well as a very small transaction fee. As you may know Vaporizers and associated items are becoming a large consumer interest. I am the founder of Vaporize-IT Distribution Corp. I have created a web or net between local (socal) wholesalers and local (socal) retailers. BUt this is growing to large for me to manage on my own. My niche is that &quot;on hand inventory&quot; is deliverable within 6 hrs and my &quot;on call inventory&quot; is available in 24 hours. We mark up the item on average (emphasis) average 35%. My on hand inventory is once the order is received is delivered by a driver within 6 hrs and my on call is delivered by a drivr within 24hrs. BUT! I want to give a retailer the option of being a wholesaler as well for certain items. If they must order some they might as well order a lot and wholesale a portion to another retailer. THey can choose to send it themselves, or have a driver of mine pick it up and deliver the item for an added cost than can be divided by both parties evenly. THe seller should be able to choose his payment option be it Cash on Delivery or Cash on Order. It is imperative that this site is exclsively for retailers (who identity should be masked with only location of store available to view to prevent retailers fueling neighboring competing stores. This exclusivity can be maintained by invite only memebership. Im willing to put up funds to have this done well for I feel it has a huge growth potential.

    Project is in final stages and requires an app developer to bring to completion.Please look at the images uploaded to get a feel for the task I&quot;m asking. From a homescreen as depicted in App_outline.png, I would like to make the images (ex, App_Image.png) queriable by the &quot;ticker&quot; (the capitalized 3-4 letter terms on App_site.png).The images themselves are hosted on a cloud server as depicted in App_site.png. In addition, the app should provide a few other services to the user such as displaying lists of &quot;tickers&quot; screened by the categories listed under the search bar on the App_Outline.png homescreen image.I have been told this project at the minimum will require a url wrapper and some code to be inserted on the host site webpages to make the image fit a mobile phone. All you the developer need to focus on is making the images queriable via the host server as well as designing the app using the outline provided as a guide. Do not worry about getting the precise data to generate category lists on the homescreen, my partner and I provide tags on the host site which you can use to generate the relevant lists. For example, links on the host server with &quot;100%&quot; will compose the list of the &quot;New Search High&quot; category.Please submit an app design to be considered for hire. If you design and develop a great app, you will be rewarded in excess of your quote.If you would prefer equity in exchange for your services, please indicate. You will be given preference.

    Hi Everyone,I&quot;m a former FMCG manager and I quit my job to build a web software company.I&quot;m looking for a skilled full stack development expert to build a piece of software with me and potentially another developer who is partnering with me (TBC). It will be the MVP of my start-up.Here is to outline what is needed:- The app will need to run on web (all common browsers) and iphone for the MVP, other devices and other operating systems will follow at later stage- It will require a well functioning map API (Google, OSM, Mapbox or Apple Maps) incl. dynamic custom interface, accurate geocoding and offline functions (downloads of specific areas, cities)- It should run with a very responsive font end, that can run offline and synch between web/mobile at a later stage (the interface and back-end will be closest to the to-do list app &quot;Trello&quot;)- Mock-ups and detailed descriptions of the functions are already available- The full UX wireframes and graphic design will be delivered by a third party- I estimated the job to be between 300-1000 hours, I expect a detailed project plan and breakdown in hoursIf you are interested working with me (or us), please share your portfolio (ideal map API based work), capacity h/week for the next 3 months and working conditions. The candidate will need to expect high engagement of myself in every part of the back- and front-end. As mentioned before it is likely that the person will be in a team with a senior objective-c developer.Looking forward to hearing from you.Cheers,Roman

    The game is a world-builder for tablet, based on the real world.Phase 1: proof of conceptIt begins with a crude model of a real city. Buildings are represented as blocks. This data is supplied as a 3D mesh in the materials for the project.The user is able to move around this world with physical constraints (not pass through floor, walls) using similar gestures to Google Earth on tablet.The purpose of the game is to fill in the detail of the city in a world-builder style. The user has a pallet of stylized objects to choose from: trees; doors; windows; staircases; sidewalks; crosswalks. The user chooses from this pallet and places the stylized object in the scene with their finger.Phase 2: an animated worldThe world contains agents representing people and traffic who move around the world subject to certain rules. For example, if a pedestrian approaches a sidewalk they will jump onto it and then stay on it. If they approach a door, they will walk through the door. If a car approaches a crosswalk with a pedestrian on it it will stop. The agents do not need to look realistic. Phase 3: persistenceThe state of the world can be persisted between plays, so that the user can come back to the same state.There is a pre-existing version of this proof-of-concept (incomplete, some bugs) which can be used to get an idea, or even to plunder some code. OTOH starting again from scratch may be preferable and is an option.
