ASP.NET - MySQL

I’m running a charting application on windows server. The charting application is currently reading individual ASCII and CSV files. I need for you to switch the data source from my current files to two MySQL database tables. The tables already exist I just need you to direct the charting application to read the tables based on user requests. One of the tables will require some simple math before plotting the data. Two of the table columns will need to be read, one column subtracted from the other and the result plotted. Please!! Only bid on this project if you are well versed in VB or C# and SQL. The charting application was created with Visual Studio 2003 and I’d like to maintain the integrity of the files in Visual Studio. I have several other projects related to this one and I will be asking you for advice and programming on the other projects.
