6 pack Captains in SF Bay Area?

Hi guys, I’m looking to charter some small sightseeing cruises here in the SF Bay Area and am looking for a few licensed captains for groups under 6 passengers. The budget is small on each of these cruises, so I was thinking 6-pack captains might be all I could afford. I’m going for my Master 100GT myself but haven’t yet got my ticket.

Anyone know of a place where I can get contact information for 6-pack, or licensed captains interested in smaller, budget jobs?

Any help is appreciated. Thanks
