Need '83 heater console; need Dallas,TX mechanic

A repair shop laid waste to all my A/C and heater controls except the fan switch and pushbutton. Evidently I need a replacement control assembly and cables. Got one, or point me to where?

I'm also interested in a personal mechanic - not a shop - in north Dallas area - for routine items (tune, brakes, etc.). I'm 50-50 on doing a tranny or at least clutch change-out too.
