Microsoft Windows Workflow Foundation

We plan to launch a big project made by WWF(Windows Workflow Foundation), and programming language is C#.net, and since the final application will be web services, Asp.net skill is also necessary. The project is in initial requirement analysis phase, I'm intending to make the real project plan together with the coder. So, if you expert in WWF, C#.net, Asp.net and have experience in this field, please provide your work with bidding.
