Cascading Dropdown list

I need somebody writing in Visual Basic "vb.net" in .NET Framework 4.0 one project containing one form. This form should contain 2 DropDown Lists, one button and one label. The first drop down should retrieve from the Suppliers table (part of the Northwind database) the SupplierID and CompanyName. On changing the supplier the system should trigger thru jquery and ajax a WCF service used to retrieve (in Json format) from the Products table the PRoductID and the ProductName belonging to the selected Supplier. And the ultimately the submit button should using againa jquery and ajax retrieves the UnitPrice and UnitsInOrder and display this in the label The other project still in .NET Framework 4.0 will be a WCF Service Application project used 1) to access the Products table and retrieve the product's list required by the form 2) to retrieves the UnitsPrice and UnitsInOrder for a product What I am providing - the Northwind database What I am expecting 2 projects in vb.net under a .NET Framework as described above Please include this text in your bid "I understand this project should be written in VB.NET" This is done to make sure bidder's are reading the specs ;-)
