Cellular Phone Program for GPS

Looking to hire a programmer to develop an application for a cellphone that can be downloaded to the cellphone and would send our server LBS information such as: ID number (unique to each subscriber) GPS coordinates, speed, battery level, if unable to get a gps fix, an alternate code would be sent to our server to do a cell tower ID locate, we would need the program to send the necessary info. to do a cell tower locate such as Serving Cell tower ID & Signal Strengh, Neighboring cell tower ID's & signal strenghts, LAC, ect.) We want to start out with a program for the motorola boost/nextel phones such as the boost i425, but would want the program to work for as many boost phone models as possible. Future developments may include an application for blackberry phones.
