Learning to Dive on Grand Cayman

My husband and I are considering spending a long weekend (3-4 days)
over Thanksgiving on Grand Cayman to take an intro scuba course. I'm a
good swimmer and fairly experienced snorkeler, but while he's snorkeled
a few times, and really wants to learn to dive, he's still pretty
fearful of the water.

Can anyone recommend a mid to upscale resort/dive operator that we
might use? We would ideally like an operator that works out of the
hotel/resort we're staying at, and preferably some place there's shore
diving. We would need small class/trip sizes and an instructor that
goes slowly and doesn't try to pressure him to go faster than he's
comfortable with. It doesn't matter if we actually get certified this
time out or not, although I don't want to spend the whole weekend in
the pool. If there was also good snorkeling from the beach that would
be a plus. Impossible?

Any opinions on Cobalt Coast and Divetech?

Thanks for any suggestions,

Jennifer
