Pulsar's suggestion is a good one. I'm not sure about all markets, but around here, the better handymen don't work with Home Depot; at least not as far as I'm aware.
I'd suggest that you "waste" an hour or two watching a few videos on youtube. You may discover that you can do part of the job yourself (if you already have the tools.) As far as doors go, I think it takes a handful of doors before you actually get it in "perfectly." Imho, doors are one of the things that people underestimate the level of difficulty to put in. Well, not that it's difficult; but there's quite a bit of an art to doing it and getting the door in perfectly plumb, square, etc. I guess the best way to put it is, it's easy if you know what you're doing, but a hell of a lot harder than it looks.
