Help with c# homework

I have a small and very simple app that I don't have time and need help coding for my class. The code is very simple and should take no time to an good c# programmer. This needs to be written in visual c# 2008. App needs to be able to select items from a drop down and automatically calculate totals based on what was selected from the drop down. It needs to also keep a running total of all purchases/selections from the drop down menu. I can provide more details exact exercise requires privately. Need to get a copy of the source code and working solution by Sunday night March 14, 11:59pm CST looking for good programmer that can get it done by tomorrow night and low bids as this is something simple. Also looking for someone that I can do this throughout the year as I will need this done about 8 more times throughout the course.
