I'm also a club diver, but in the U.K. There are a number of things you need to research for you area:
* what is the legal definition of a members club, and therefore your role.
* offering travel packages to the Public could make you a travel agent, it does in the U.K. Only exemption is if the package is to club members.
* be clear in what your 'buying' from the boat operator. Again in the U.K. Charters are only the water taxi to/from th dive site. Their responsibility is putting divers in and recovering them safely, everything else is the organisers responsibility.
* insurance. Each country has its own peculiarities, but generally if an activity is covered by two or more policies the companies will argue over their liability rather than defend you.
