Application rewrite windows mobile 7.0

I have an application running perfectly on Windows mobile 6.5. The code is written in C++ and it works perfectly well on this platform. I am looking for some one who can make this application work for windows mobile 7.0. All business logic is with me. All the source code. All you need is some UI rewritten. More details will be provided to selected shortlisted bidders. Kindly note in Windows Phone 7 you might write the UI using Silverlight. All the logic and code is present and it is not a much work for a professional. More details in PMB. Looking for cheap bids.
