Hi,
I am a 20+ years old software engineer experience. For the last 15 years I have worked almost all the time at home, having enough experience to succesfully finish this project. As my work always was done in a very professional way, references can be sent in Portugal, Brazil, USA, UK and Australia.
Some months ago I have developed exactly this with one more feature: a WCF connection to enable users to change configuration and check reception status. Checking your GPS protocol, I realize it is not so simple, and will give several hours to be understood.
I can garantee you will have your software with source code using Visual Studio 2013 and c#. It includes a windows service WCF enabled, a windows app to connect using this WCF line and show data being received or change configuration and a windos app to install/remove the service, with full source code at the end.
I look forward to discuss my qualifications further.
Best regards,
Rogério Reis da Silva
