Small PHP code to VB.NET

Hi, I would need a programmer who knows well PHP/VB.NET(2008)/MySQL and wud be good too if he can speak french. The work is very simple if you know PHP... There is this script [login to view URL] where you can add students grades... and it will generate you the average... to generate the average it use PHP code formula to retrieve data from the mysql then calculate it, as i don't know PHP i don't understand it. So I need someone who can rewrite me a small code in VB.NET that will be able to show the average for the 3 semester in all subjects for the student selected. I use mysql connector to connect mysql database with Vb.NET you can use that. Please check it before bidding. It's very easy so, i woun't choose high bidders. thanks
