Robert,
Any good lab which caters primarily to the professional market should serve your needs well. Stay away from any of the bulk mass-market places and you'll do fine. You'll pay a bit more for the pro labs, but it's worth it for what you're wanting.
Two highly regarded labs with strong national reputations which I'd recommend are
West Coast Imaging and the lab I use
Photo Craft Imaging in Boulder Colorado. Tell either of these places what you have and what you want, and you won't go wrong.
