Looking to pay San Diego local for prototyping/programming help

I have a project that involves two arduino megas that I would like to interact with the each other.
I need to make both of them into transceivers.
I have transmitters, receivers, wires, displays, and two arduino megas.
Just need help getting it all together.
This isn't a long term job, but if there are any freelancers that are willing to meet up, please let me know.
Thank you,

I have transmitters

What kind?

receivers

What kind? Are they compatible with the transmitters you have?

It would probably be simpler to dump what you have and just buy some transceivers. The NRF ones are pretty cheap, and have good support.

I have ultrasonic transceivers now.
I am trying to get two devices to "communicate" using sonar only.
