Simple Arduino Security System Programming (will pay)

I’m looking for a developer who can help me program in Arduino the following security system:

A 3-component Arduino based system comprised of a wireless battery-operated PIR Motion Sensor Unit, an AC-Power Base Unit and a Wireless battery-operated Remote Unit. All 3 units need to be able to communicate via encoded RF transmission (matching up the units should be accomplished via dip-switches on each unit).

I have a system logic laid out but to be shared one-on-one basis as well as some possible technical hurdles we’ll need to discuss.

I am willing to pay for this help and can pay via Paypal or whatever method we agree on. Please PM me if you’re interested. Thanks!
