Try Jackson Blue, it is a little off the beaten path for most cave divers, but no one asks questions about gear.
FYI- "Apprentice" isn't really a certification, it is a way to break Full Cave into a 2 part course, rather than doing it in a 5 day period. It expires 1 year from issue.
My advice would be to complete Full Cave (not necessarily immediately, in fact, I think you should do some Intro dives first), even if you do not expect to exceed the Intro limitations. Reason being- you will gain a great deal of expereince and knowledge that just isn't covered in the Intro course. One day you may encounter a situation that will draw on those extra skills.
Good Luck
