Thanks for the advice, will check into that.I think the others here can be more helpful with this.
But a couple suggestions
1) call the local sailing club, if three is one. Tell them your interest and see if they can connect you to a captain
2) look at https://www.meetup.com/ for your area
3) maybe place an ad on Craigslist
take a sailing vacation where you learn to sail as well (I think this has been suggested a couple times)
