Auto swap to 5 speed

I didn't seem to be able to find a post about this subject in the search function.

But I am looking to swap my Automatic 2002 V6 over to a 5 speed, any suggestions? T5? Or other transmissions, where can I look for used ones and which trannies should I look for and ask around about?

Also what needs to be done besides adding a clutch pedal ?
Any estimates on the cost of the tranny you are suggesting and also additional parts, and possible labor costs or hours atleast??

Thanks a lot,
Casper
