Looking for guys who could assist me in building RF based circuit

Hello! I am looking for guys to assist me in designing RF based circuit which won't be based on modules but would be based on chipset. I would provide/do most of the circuit build, layout plan etc.. upto 80% , however I need the freelancer to help me in impedance matching (important),filter design , footprint/pcb layout making. Total of 5 boards of such class maybe needed to be designed.
