GPS PCB DESIGN

I am looking for a freelancer to design a GPS PCB for tracking purposes. The device should have the capability to integrate geofencing features, as well as other features requested by the customer. We are searching for a compact form factor, to fit customer's desired design. This design should be highly optimized to maximize battery life and minimize development time. If you have any experience with GPS PCB design, and think you can help me achieve the desired outcome, please reach out to me. Thank you!
