I would go out and track/mix at an OUTSIDE good studio. Before you diss, let me elaborate;
First, the gearslut direction is a endless pursuit. You sound like you have your s%it together, so, work on your tracks, track and mix them at a reputable studio (you live in Brooklyn so you have many choices either in the BK or in the city), and spend your money and time on the best promotion and marketing you can do. Use OPM, in others words, Other Peoples Money.
This is where the hits are separated from the also-rans. You're going to need every cent you have for P&M.
Listen to the radio, this current rap stuff is not recorded in the best studios, with the best gear...but it IS marketed with the best promotion and marketing.
If your tracks are hot, and you play the game right, $20k can go a LONG way. But even that is pretty thin in this game.
Just my $0.02.
