Amazon provide Windows hosting on the cloud. Personally I host MVC 3 on a Windows server 2008 R2 with Hetzner for €65 per month. The Bizspark programme will help you to keep the licensing cost down to pretty much zero in the short run so I don't think this should be a major concern. Like another commenter suggests you can look at Mono which will let you run MVC 3 (with the Razor view engine), however note that EntityFramework isn't supported and you would be advised to start from scratch in Mono and port to .NET actual later if you chose that route rather than the other way.
