Kind of echoing what others here have said. I'd find friends or family that you already know well to bring on the trip with you to share the cost, and the crewing load. Not knowing your level of sailing experience, I am making an assumption that you are a fairly confident/competent sailor. If so, you can generally teach some newbies the ropes in short order, as long as they have the right attitude. If the sailing skills aren't there, then a crewed charter might be for you, and then the experience level of your companions really doesn't matter.

The other alternative is to charter a boat that is cheap enough that you can afford yourself. Check out Captains Compass, I think they are still a sponsor here. We've chartered with Brent once and had a great experience and a fantastic value for our money. Feel free to PM with questions.
