WPF project demonstrating a parent/child relation with VB10 and Visual Basic.

Hi dear programmers, I need a programmer who can code a wpf project using the mvvm pattern. As already mentioned in the title of this job the project should "demonstrate" two related datatables. The relation is a 1 to n relation between "contacts" and their "phone numbers". Here a few more details: -The project must run on a Visual Studio 2010 Express Edition -The code MUST be written in Visual Basic! (NO C#!) -The data of the contacts and phone numbers is stored in a sql database -The project shall use/demonstrate inheritance (at least for two classes) -No use of Datatables, but entities instead! -The architecture of the "parent data" viewmodel should support filtering, sorting and grouping (filtering, sorting a.s.o will be added later on, when I will extend the project) So these should be the most important "conditions" for the job. I hope I did not forget any important feature of the project. So is anybody interested in accepting AND ENDING this job? Best regards, Jeiss
