So I've seen the various sites that have different listings of vendors and such that have buyers/sellers/people who accept BTC.

That being said, how might I best go about offering my expertise as a writing tutor in exchange for BTC?  The wiki doesn't really have an area for individuals who have very specific skills. I've seen http://www.bitcoinclassifieds.net/Services/ as an option-- has anybody had good experiences there, or somewhere else that might work?

Thanks!
