I got a request to become a tutor for the web programming course from a student at our local college. It used to be PHP and JSP though as of this year JSP has been removed (so all PHP, yay

). I've also been requested from the same student to tutor for C and client / server (probably C# since webservices are so easy to build in it).
Now, I'm trying to figure out what to charge.
First, minimum wage in Saskatchewan is $9.25 if I'm not mistaken (as of May 1 2009). Normally I charge a fairly reasonable rate of about $10-$14 / hour depending on complexity (this is fairly basic, standard handling + OO & SQL, maybe some XML and external Data Handling) since these are students. I'll actually slide if I know they're in a bad spot. However, due to equity programs (female student in a primarily male industry), the tutoring fee is covered by the province. So I'm debating if I should increase my rates a little bit, to the $14-$20 / hour range. I'll be talking to some other people that have tutored through this program to see what they have charged.
What do you guys think? Am I crazy to request $17 / hour for this? What would you charge, total and relative to you're minimum wage?
