I have done a similar project for a dubai based company to track container , i have worked on WPF for more then 2 years now, building different kind of Touch enabled POS and Healthcare system. I would do 15% of the project without any upfront charge, and send it to you to evaluate my capability, project reporting and all on a daily basis is no issue , delivery 100 % guaranteed. payment 100 % after demo of the complete project.
