Well doing your own A/C work is rewarding, and i know autozone stocks the leak detector and the gauges, but i don't know where you get a vacuum pump locally. They aren't cheap though.
Here'* a link to vacuum pumps:
They one we use at our shop i think is a 3 or 4 cfm pump, which you can see are NOT cheap. Also if you plan on doing this just go and buy yourself a 30lb tank of R134-a freon. It'* got leak-detector built in that does not need a UV light to be seen. Hope this helps!
