I'd avoid any wholesale pay-to-play operations (ex. GIA aka Silver), that reputation will follow you around forever. It's not a deal-breaker, but some folks have a real hard spot for that, and if one of them is on your interview panel...

You could probably get away with it at a small corporate operation, nobody would ever know but you. But there's enough of a pilot shortage you should be able to find somebody to pay you to sit right seat in a jet somewhere. Even Great Lakes will pay you a little bit. Once you get 1500, you can go to a real regional and make $60K.

You'll some regional time anyway, no big-six major will likely hire you with just turboprop time (maybe SWA).
