Hello,
For the development of the complete solution using Xamarin and for the support of all 3 platforms and devices I can estimate 6-8 weeks of work.
I will need to discuss about some technical details of the project.
Relevant Skills and Experience
Expert in development of desktop and mobile applications using:
C#, .NET, WPF/XAML, Silverlight, UWP, Xamarin, WCF, XML, JSON, REST, Android, iOS, Mac, Windows Desktop
Proposed Milestones
$800 AUD - Initial milestone
$3600 AUD - 1st milestone - First release
$3600 AUD - Final milestone - Final release after the final acceptance test
Additional Services Offered
$1000 AUD - Periodical maintenance based on the agreement
Do you need for this project only a partially functional proof of concept or the fully working and tested application ?
