Help with circuit design

Looking for help to design a circuit (Eagle file that I can send to a board manufacturer). It's for my volunteer ambulance service - I'm designing a vehicle telemetry module to send GPS and vehicle information (e.g. speed, engine trouble codes, etc) back to a server.

The board I need is really just a bunch of sockets (female header pins) where I can "drop in" the GPS module, the GSM module, the OBD module, and my Arduino chip.

Never done any type of circuit design before, and we want this project to launch soon. Willing to pay for the consulting time.

Thanks!

Good luck!
