If you live near a community college, the college will probably have students who help out as advisors, that could be an option. One of my sisters is a math advisor at our local community college, at least when she's not working on her own coursework.
Another option might be to just take a community college course. As someone who's done both self-study (Calc I and II) and community college (Calc III), I much prefer the latter method for difficult subjects. It's just nice being around a group of students all studying the same thing, and community college courses only cost like $300 each.
Incidently, I went straight from Alg II to Calculus. The pre-Calc trig identities and so on were all in the first chapter of the book anyway, and I'd rather get straight into using the identities than spend months trying to learn them for no apparent reason. It's the same reason why a foreign language teaches English grammar better than an English grammar course
