I would give Skymates a call out of Arlington, Texas. Those guys are really good, fair price, and you won't spend a bunch. No matter what school we went to, we all had to pass the same FAA standards to get our tickets.
I went to DCA and while I was there, the training was top notch, however I wish I would have gone somewhere else, for CHEAPER!!!! (which I did, try Falcon Flight Sanford, just buy a block of time then pay the instructor apart from the rental fees, or try Skymates, both have web sites.)
Anyway whatever you do, hope it works out. Doug Taylor over at jetcareers.com can tell you about his experience as well as others about DCA. That's all I'm going to say.
Blue Skies!!
