Does anybody know how to make very small fm radio transmitters?

I do not need nearly as much as you would think.
I do understand the legality of running an fm transmitter, however, I only need it to transmit less than 50ft.
I am looking for help on a product that currently exists for very cheap, or someone who knows how to create a very small circuit board that would do this for cheaper.
I need 10 which is why I am trying to save some money.

I want to make something similar to these: http://en.wikipedia.org/wiki/File:Harumphy.belkin.tunecast_ii.jpg

But that's all the more powerful I need them and I know there's a more DIY way to do this out there.
Any help would be appreciated.
Thanks
