Xamarin native developer- Image pinch zoom cropping control

Looking for a xamarin developer to build a custom image cropping control in xamarin forms. Looking for IOS for now I just need a simple View that calls the control on the app load. This is an easy task and pretty sure someone already built something like this. Watch attached file to see how the cropping should work. It should have rectangle instead of circle. NEEDS TO START IMMIDIATELY! PLEASE READ THE JOB DESCRIPTION BEFORE BIDDING
