Calendar Control Project April 2019

We are looking for a Xamarin Forms control to be built that works for Android, iOS, UWP, WPF and MacOS. The control will be a calendar date picker. It will look like a standard picker control when closed and a calendar will popup when the user clicks on it. The final product will include a standard .NET lib with the control in it plus a sample Xamarin Forms app to show the control works. The sample will include a [login to view URL] lib project, Android project, iOS project, UWP project, WPF project and MacOS project. The control will look like the following when closed. The date in the box will be read only and use culture so it changes depending on the language/culture settings on the device. <<Calendar Control [login to view URL]>> The control will look like the following when open. <<Calendar Control Open>> Review attached Calendar Control [login to view URL] for project specifications. Please answer the following questions with your bid or your bid will be deleted. 1. What experience do you have with writing custom Xamarin Forms controls? 2. How long would it take you to write the control? 3. When can you start writing the control?
