T-shirt designer

T-shirt designer

Hello
I really need a t-shirt designer. I have searched the web after a script to use but can not find any. Does anyone in here know of a script? Or can you point me in right direction where to start if I try to build one myself. I know a bit of C# and MVC.
 
The designer have to do this
  • Upload and save pictrures of shirts.
  • Add text to shirts and edit the text such as font, size and color.
  • Have categories with our own prints and just click on them to add to the shirt.
  • Resize, rotate and crop images.
  • It have to be in Jquery and HTML5 absolutly not in Flash!
