T-shirts and Mugs&more designer

[COMA]

Hi guys,
I've done a search on the forum but i can't find anything about web apps or any software that allow customers to customize, choose and place an order for whatever mug, tshirt, ipad cover they want.
I've seen many webstores that let you customize your own tshirt, but they won't let you select HOW they will be printed (sublimation, screen printing, DTG ) or they are designed only for garments.
Do you know if anything existing yet?

no.
RSKnetshirt or Deconet are competant, but the production is up to you, - both then best for dtg?
