I think topside for 14 years speaks for itself. Any dive op willing to take you on a Wreck would be taking huge liability risk, particularly with your lack of instructor-level training.
If you're worried about it, sign up for a Padi wreck diving course. It'll cost you maybe $250 and you'll probably get 2-4 dives and maybe a few new procedures out of it. You'll likely get a divemaster guide, reference materials, boat trip with emergency radio, free air refills and gear rentals, dive maps, and for hardly more than the cost of two 2-tank dive trips. Then you can prove to Padi and the dive world that you're as cool as you say you are.
