Conversion of forms from VB.net to asp.net c#

We are upgrading our current desktop application (Visual Studio 2008 .Net framework 3.5, vb.net) to a web based application (Visual Studio 2008, .net 3.5, c#, asp.net). We have about 6 forms that are, in essence, calculators that would need to be their own page. The users would enter in the values, click Calculate and it would display the appropriate information. The other 5 forms would keep track of locations, rooms within those locations and the contacts at the locations. These would also include stored procedures (SQL Server) need to hit our database to display correct information or add a new value. Would also include searches for a particular location based on user entered criteria. Some client side code may be required for validation or calculations (javascript/jquery/ajax).
