Help! Need '74 911 A/C guy

[VDD]

I need the name of someone who can work on my A/C in the Pasadena, California area. There is a high end (for the time) aftermarket A/C on my car that needs MORE than recharging (I.e. new Compressor, pressure release valve, change from R12 Freon to whatever is O.K. now). I installed a Carrera Aux oil cooler so I think I'm O.K. on the oil cooling end to accommodate the A/C again. I also heard some people install a condenser (with a blower) somewhere in the front end. Not sure where. Anyway, a couple of names would really help. Thanks
