First, how much would you expect to pay to have it done?

I have a 71 Satellite that I want to have completely rewired, and have some of the upgrades done to help with the the common problems with the charging systems on these cars. I have already run a heavy guage wire from alternator to battery, and installed a relay for my elctric fans and a voltmeter, and would like to keep those. I would also like to have the headlights, A/C,etc.. put on a relay. Does anyone know of reputable shops in the Orlando/Gainesville FL area or in the Killeen/Austin and maybe even Dallas or SanAntonio TX areas?
