I only need a very basic app and it will be up to you to tell me how much you can get done and for what price. Desired features: Server back-end (Java/C#/Delphi) - needs to run on Windows - interfaces with RDBMs (any flavour) - db schema (anything that works enough to demo) Android app - display of task list (let's say 3 fields as a minimum "name, description, due time") - able to receive new tasks from server - persists the tasks to storage - able to drill from list into a single task - able to execute "start" and "complete" actions against the task from the single-task view - able to send actions to server, and to queue (resend timer loop) if offline - able to work offline/disconnected - auto switching between wi-fi and 3g - reads configuration from a local SQLite db (server host & port, "id" of device) The front-end for creating jobs to send to the Android The ideal candidate is one who has ALREADY done a similar app or can customize something, so that I'm not paying for you to learn how to develop an app from scratch. You can ignore the $250 ceiling and you may also give me as many pricing options (xyz for $a, add abc for $b etc) as you see fit.

I am only after a starting point from which to build my full solution. Thank you for reading this far and bidding. Note: I won't read the bid messages at all.
