This seems to be a two part project. Just to be clear, I am familiar with telematics module implementations.
First, I can research various modules, no problem. I will need a comprehensive set of requirements, such as voltage and power requirements, battery chemistry (or supercap technology?), comms protocols, space constraints, etc.
The second part is design of the PCB once the circuit is defined. The requirements for this step include the oulines for the pcb, the design rules, and the GA drawings to find the space constraints. If this is a mobile product for a harsh environment (vehicle engine bay, marine, reefer compartment), the IP rating will also be important.
As an optional third step, I can provide a 3D model of the final product.
