Need functional prototype of the PCB

I am looking for someone to assemble a transmitter and receiver pair, like the one at [login to view URL]

Not all of the EXACT components are still available from the manufacturer, so some adjustments will need to be made to incorporate appropriate substitute components, as well as any appropriate adjustments to the other simple components like capacitos, inductors, etc.

At the end of the day, I know that all of the components are pretty cheap, and someone who knows what he/she is doing will probably be able to do this fairly easily. So... the deliverable should be a working set of receiver and transmitter that accomplishes this alarm function when the receiver moves far enough away that it begins to lose signal. I would hope to be able to approximate a distance of 30 to 40 feet for the alarm, but we can discuss that part.

I prefer someone in China who can do it in a short time.

I would appreciate help and await your quote.

My proposal is - instead of making everything, you should use existing 443MHz transmitter/receiver module. These modules are cheap, small (0.5" x 1") and more over, they use crystal which gives much more frequency stab Mais
