Providence area Piano teachers with kids?

I've decided that I want to learn to play the piano. Since I'm poor, I'm looking for someone who'd be willing to give me lessons in exchange for services instead of money. Tutoring seems to me to be a natural choice. So if anyone knows anyone in the Providence area who might be willing to exchange piano lessons for tutoring services, please send 'em my way. Information about me for prospective tutoring-recipients:

I am a Ph.D. student at Brown (philosophy department). I graduated in 2003 from Rice University with a B.A. in Philosophy and Cognitive Science. I have experience tutoring math, logic, science, history, writing, and English at elementary, junior high, high school, and college levels. I'm also able to help with standardized test preparation. (My scores: SAT: 1550, LSAT: 172, GRE: 670-verbal, 790-quantitative, 800-analytic.)

Information about me for prospective piano teachers:

I've played the clarinet for many years and I also do quite a bit of singing, so I am already comfortable reading music. Also, I know which note corresponds to which key on the piano, and I have some vague idea of what the pedals do. Beyond that, I am a complete beginner at the piano, but I hope to be a quick learner. Also, I'm nice.

I would be ecstatic if I found someone within reasonable driving distance of Providence who was interested in entering this arrangement. If you are or know a likely candidate for such a person, I'd very much appreciate being put in touch with him or her.
