EE/electronics guys - looking for places to buy RF transcievers

I am doing a project in one of my EE classes that involves RF communications. I am looking for places that sell RF transmitters, recievers, and transcievers. I have already found one at www.abacom-tech.com and was wondering if any of the other EE or electronics experts on this board knew of any other similar places that sold such hardware. A google search for RF transcievers is turning up way to many results that have nothing to do with what I want, so I figured it may be easier to just ask some people who may know. Also, if anyone here knows a lot about RF and wouldn't mind answering some basic questions for me (no I'm not going to ask you to do the project for me), could you please PM me?

thanks
 
Alright, here is an overview of the project:

We envisioned our product would be used in amusement parks or perhaps large malls. It will be used to track children to make sure they can't get lost and separated from their parents. Here is how it would work: each child would be given a wristband that would contain a small FM transmitter (or possibly tranciever) and scattered around the park would be FM recievers (again, could be transcievers). The recievers would be positioned for minimal overlap but still allow all area to be covered. Each reciever will be connected back to a PC via RS-232. The wristband transmitters would continually transmit some unique binary ID code. Prior to entering the park, the parents could register their name to a particular ID tag number so that security would know who to look for. The recievers would pick up any ID codes that were in their effective area and transmit this information back to the PC, along with the strength of the signal. In this manner, a software program could be created that could use the data to determine the location of the child with a reasonable amount of accuracy.

To do this, I figured we would have to use either TDM or FDM, because if all FM transmitters were broadcasting numbers on the same frequency we would probably get data collisions or something.
