I can second Professional Camera Repair. They do good work, they're prompt and reasonable.
Now that Camera Co-op has closed its doors, the only real camera shop left in the Houston area is Houston Camera Exchange, although there is a new place called Prime Camera, but they appear to be digital only. Anyway, HCE carries a small supply of darkroom stuff, although nothing like what CC used to carry.
Paul, if you think you may shoot a half-dozen rolls of B&W a year, it would actually pay to do it yourself. You may break even the first year, but after that you'll be saving money. Developing B&W is about as hard as falling off a log. Equipment investment is minimal: a developing tank, thermometer, a couple of storage containers for the developer and fixer, and a measuring cup and funnel would be handy. I use a regular old sponge for wiping down my negative strips, and I hang them from a pants hanger with the built-in clips for holding the pants, and I use clothes pins as weights, clipped to the bottoms of the strips.
Now, when it comes to color film, choices are poor. Every place I've found, except Aker, sends out the film and you get back prints and a CD. No negatives. Unacceptable to me. So, you're looking at sending your color film off, or Aker. Or doing it yourself, which is what I do now. Developing color isn't hard, you just have to pay very close attention to developer temperature, which is somewhat hot, at around 102F. I use a styrofoam cooler as an insulated container for the bath that keeps the developer temp stable.
Oops, I didn't notice how old this thread was.
