HTML to Xamarin App (Android & iOS)

I need to wrap / translate this HTML (with Google Maps, native geolocation, jQuery, Ajax and other scripts / css / images) to a Xamarin project app able to generate Android & iOS apps (apk & ipa as intermmediate result). You can use Razor or wrapping, just tell me what will you do (or another techniques / languages if you think the are better and quickly, but with the same goal: an HTML to app). "Geolocation" must read the native location from the user device. Ask for the permissions in each platform if necessary (it is!). If you need to modify the HTML to allow geolocation or other features, do it. But please, tell us the guidelines to do this in another HTML project. After you deliver the project, I will change the HTML and resources, so you must deliver the source code and the steps to do it. Attached an HTML and js / css / images for example. If this HTML works in an APK; and source code and manuals (how to do resources / HTML changes) are delivered, the project is completed. Time and cost will be considered.
