Mustang Performance Shops in Indy?

I am a new member and am looking for any local shops around Indianapolis that are Mustang specialists. I recently picked up a 2001 GT Convertible and want to start making modifications but have many questions as to the best way to go about it and where I should start...engine bolt-ons or exhaust? Wanted to do headers and full exhaust system first but I understand putting the long headers on is a real PITA. No one wants to waste time at a shop that has never done it before...I hate to pay for unnecessary shop time! I also looked at the BBK cold air intake and 78mm TB but wasn't sure if I was shooting myself in the foot by increasing my TB size if I wasn't making major mods to the engine.

Thanks
