Android to PC communications via Bluetooth (serious bids only!)

I am needing an app that mimics this app currently available here [[login to view URL]]. It has a nice set of features but also lacks a lot when it comes to the SDK/API. Please also check out a video of their app [[login to view URL]] in order to get an idea of all that it does to better help you vision what I am looking for. The features I am looking for in my app are the following: - Ability to call a number (from the contacts list (showing image(s)) or Dial pad) - Ability to answer a call (shows the users image and phone number on screen) - Ability to hang up a call - Ability to get the contacts (with images) The SDK/API needs to do all the above via listeners (especially listen for incoming calls). It can be coded using VB.net or C#.net. All communication will need to be done over Bluetooth. I will not want to use Wifi or USB for this. My max spending for this will be set at $200 or less (naturally the lowest offer will be first to be picked based on experience). If you quote something higher- than don’t bother posting it here. If you do post it at a higher price than $200 then I will delete it. My development environment is Visual Studio 2010/2012 running .net framework 4.0. If you have any more questions about this then please feel free to contact me. You will need to put a step by step process on how you would do this project in the email/quote you send me to know its just not a copy and paste thing that most company's do on here. If you dont have this in your first email then you will not be considered for this job period. Serious bids only!!
