I plan to write mobile application which should run on Android, iOS and Windows mobile phones. Xamarin seems to be good choice for this task.
I am pretty good in C# and related technologies, but never worked with Xamarin.
I need a consultant who knows Xamarin really well and who can spend 2-3 hours daily helping me to do things on the right way first time. Then, if project is going well in first month, we can agree to increase cooperation.
