Check out some of those blog posts and articles on how to do it:

You should find it extremely simple to convert - especially if your existing asmx web methods are just calling into other classes. Just create a new WCF Service from Visual Studio - that way you still have your existing web services intact. It will automatically create an http end-point for your so you can just dump it straight into IIS (with a little configuration). You will need to describe your DataContract classes but that it trivially simple too.

I did this recently and it was a joy!
