i've seen ads in the library or the pennysaver. i think i was getting paid about $12 an hour to tutor (elementary/middle school) a couple years ago. plus, it was in home so i had to drive to the families' houses. i definately think what i was getting paid was low, especially since teachers here in NY make a TON. (this year, teachers with no experience and just a BA and certification can make just under $40,000 a year. i saw on the NC website that a teacher with the same qualifications makes about $28,000 a year.)
so i'd say at least $15 an hour, especially if its in home. most kids cant focus for more than an hour. and you have your time and gas driving there and back home.
