Advanced PHP Tutor - Hourly rate

i am an intermediate php/mysql programmer and want to get hourly tutoring to get to the next expertise level. I would like to work with you on an hourly basis going over a script that I downloaded from the web. PHPProAds. I will send you a copy and ask you questions about the coding. We can discuss over google talk. I am estimating 20-50 hours of time but would like to work with you more until I am an expert. We will work in 60 minute time slots. If we have a session less than 1 hour, I will pay you for the full hour. Please bid your hourly rate.
