Dutch Country Helicopters at Lancaster is worth checking out. From memory, it's about an hour or so north-east of Baltimore - less if you're going to be living to the north.
I've only flown there once but I liked what I saw and will definitely go back next time I'm in Philadelphia. Well-maintained helicopters (3) and a good instruction and you can learn to fly helicopters in a Bell 47 which IMHO is a big plus.
They charge only $220
pr/hr including instructor which compares well with R22 training costs. I think it's about $200 if you buy 10 hr blocks.
