Dive shop Rcommendation in Akumal

I'm going to be in Akumal next month with 5 newly minted divers. They will need a lot of hand holding, so I'm thinking of hiring a private guide/DM for them. Does anyone have a recommendation for a dive shop? One of the divers is a small 12 year old, so a shop with a variety of bc's would be helpful.

i was just there in jan, i stayed at Aquatech dive center and dove with them:

i posed a trip report on scuba travel a few months ago, my pics are on:

i liked the resort a lot and diving was great. the only problem was it is kind of remote and away from things.
