Bind and iOS framework as .Net MonoTouch dll for use in Xamarin iOS project - repost

We are developing an iOS project in .Net C# using Xamarin (a commercial product for .Net MonoTouch). We need to make use of an iOS framework in this project, and therefore need to create a MonoTouch/Xamarin binding from the framework. The result that we are looking for is therefore the .dll that wraps the framework for use in our Xamarin project. The framework enables the use of a printer (Star SM-T300i), and the only legitimate test would be that the printer works, so we would only be able to sign off on the project once the printer works on our side. I trust that it won't be a problem as the problems we have in creating the wrapper is mapping the variable types etc., and someone with some experience of doing the above sill hopefully do that relatively easily. I have included the entire framework. Kindly take a look and if you feel that you can do this for us let me know!
