Xamarin Forms Front-end

We are working on a Xamarin Forms project and are searching for somone who can assist us with the front-end part of the project. Our designer made some designs and we would like to have the XAML end-product look as much as possible like the design. There is no need to use any datatemplates! Static XAML files are enough. The only requirement is that the deisgn is scaleable on different screens en resolutions via preferably grid layout.
