Hi there,
It's been a while since I've seen an old Windows Mobile app! But I have worked with these in the past and I do work with Windows Phone 7.8 and 8 at the moment, so I'd be happy to do the conversions.
I have over 10 years experience with C# development, covering WCF, WinForms, ASP.net and most recently Windows Mobile apps. The logic of the game sounds straightforward enough. I have experience of using WIndows Phones somewhat esoteric built-in databasing functionality so can migrate your game database, and provide you with a basic UI for the game interface that can be expanded on as needed.
All my code is fully Stylecopped, compliant with Microsofts design guidelines and fully x-commented throughout, so the source code will be easy to pick up on and understand.
Do let me know if you have any queries regards my proposal,
Regards
Chris
