I want to make my own t-shirt design site (similar to cafepress.com, spreadshirt.com, districtlines.com), but instead of it being for customers making their own designs, I want it to consist of my designs. I want to be able to design the tees, but never have to do the actual heat press and shipping process. I know I can make Zen Cart for the purchasing process, but as for everything else, Im at a loss..--Answer1:You could have a website with your t-shirt designs, then arrange for a print business who does this type of thing to print them..--Answer2:Do you want instruction on a "do-it-yourself" website or someone to do this for you and promote your business? I can do both but for now here is a choice. Get a free website and mess around with the editor and find out what the upgrade offers. You can always ad paypal or other on-line payment methods to these free websites and some have already installed a system like you need. Look at shopping cart sites as well many of those are free and you can test their performance and then upgrade for more options. Hope this helps, let me know if I can offer more.
