I am an expert in Software Development using C# 4.0, VB.NET, completed 48 projects with all 5 star ratings, So I can do this project for you with Quality and Performance. I have 9 years of experience in .Net and this project suits me very well.
I will create the following:
1. Desktop Software to change the wallpaper image & calendar grid in it.
2. Software Licensing - One purchased and downloaded application can be installed in a single PC only, and can not be distributed in other PCs. This will control software piracy.
3. An ASP.NET site to Mange the download and purchase. (Site should be purchased/rented by you, I will create and upload the ASP.NET Site code)
A bit about my work ethics:
I complete my projects on or before time, my bid cost is almost minimum in all experienced bids. You may hire me again for your future requirements because of software quality, communication, availability, punctuality... if you allow me to serve you once. You can get me 14 hours a day online in Skype chat.
Lets discuss and start this project. Send me all the task details (If anything else you want to share).
-Thanks and Regards
