I've done it, but wouldn't recommend it unless you have the proper tools and skill. Can't help you with a local company. I'd just get quotes from some of the larger firms in your area. It's not that difficult for them and there's nothing cosmetic to worry about, so who does it isn't necessarily a big issue as long as it's something they routinely do.
Sorry, haven't checked this in a while. I called the Over Head Door co. and they're coming out as soon as I clean up the garage a bit. I'm in the Houston area.
For those in the Central Texas area, my guy will easily beat ODC's prices & work with you on the stuff jamming your garage door (i.e. help you move some **** outta the way).
