I would tend to point you toward either PSA or BCM. Both offer quality barrels and will be available in your price range.

It seems like you've got a good scheme. But if you want a unique setup at a good price, you're gonna have to wait patiently and be ready to strike at the opportune moment. Might be available tomorrow, might be in February. But you can get what you want for $500 or so w/o BCG and CH, and another $100 with them.
My advice is that you stand firm with what you want, and wait for the opportunity to present itself. Trust me...it will. If you are willing to compromise for something that's close to ideal, this looks promising
