Unfortunately, you're looking to increase your service level, while decreasing your price. You'll either end up with a budget provider who only claims to support you, or you'll sacrifice quality elsewhere. You'd need to raise your budget significantly to get full management and the 'best support'.
Here's a fast question to you. What do you need in terms of support? What do you need done on the server?
The thing I hate most about supporting a Windows Server is when someone does something crazily wrong on the server, there's basically almost no way to fix it back. Eg. someone deleted a .dll file or something like that which is needed. You'll be so out of luck even if you're on a Managed Server.
