Both Tom's SVX and AvPPoW do work on svxi.
Tom has done more than enough work to qualify him for not only transmissions, but engine reseals, cams, ect.
AvPPoW Also does really good work. He is quite experianced mainly with transmission swaps, though I cant say about cam installs, ect.
Both do really high quality work, as Ive not only seen but helped both. Heres a link to each thread with prices and explaining labor rates...
