pcb design x 2

I need two pcb's designed, they need to interact via bluetooth BLE. Unit #1 needs the following capabilities and sensors. GSM / GPRS BLE Compass Gyroscope Accelorometer OBD interaction Unit #2 needs BLE To interface with e-ink screen Unit #1 will need a backup battery, but will have constant power in vehicle. Unit #2 has to operate with as little power as possible. Size is important, units should be as small as possible. You are welcome to suggest solutions. I already have working pi and arduino versions, these need to be custom pcb's with a full report on parts used along with pcb layout and gerber files. If you have questions please ask. Please submit your ideal budgets and timelines.
