Android Point of Sales Application

A point of sales application that will allow one to plug a "square"-like credit card reader into an Android device, get the consumers' contact information, enter the price of the sale, and submit the gathered information, credit card, and signature to a web service for processing. At the start of the project, I'll share with you all the assets, a mock REST web service API (5 methods) and network sniffs to call the back end, send you 2 mobile card readers, give you the SDK to use the readers, and give you the iOS source code (yes, we have the app 85% written for iPhones). Attached to this post you can see the "sitemap" to understand the flow of the application. We would like all the source code (fully commented and with unit tests) posted to our repository on a daily basis. I would like a working version about 7-10 days after kickoff and the final version 5 days later. If possible, during the bidding process I will reply-all to reasonable questions.
