best transportation cozumel

[Shooter]

Thanks for all the recommendations. What about specific charter operations? I do not need to be coddled. I assemble rinse and dissassemble my own gear. I dress myself and require no assistance. ( Except ice diving  :-[ need a bigger harness). I would like to get at least a 3tank dive per day. Would like to schedule some of these good sites in advance. Want to stay away from the dive police... as much as possible. Also would like to know about shore dives / snorkels. I understand there is alot of current. we like to put in in one spot and drift to another then take a taxi or other means of transportation back.
