Not that you suggested doing this, but most of the Keys dive ops are pretty strict at taking divers to the deep wrecks only if they have (a) an AOW cert or (b) two >80ft dives in the last six months. (The latter item varies slightly with dive op.)
So you'll probably be going to Molasses Reef. It's a big reef with lots of variety. There are other reefs like French that you can dive after Molasses. And if you want a wreck, the Benwood is the only shallow wreck worth doing. It's not a great wreck, but it's good enough.
There are a bunch of other threads that talk about which dive ops are better, but the bottom line is that there are a TON of them and they all seem good. It's rare for a Keys dive op to be bad-mouthed on this forum. Just do a search and you'll get all you need.
