Hi
I have a very good idea for a clothing company. I know how to set up an online store etc, but what I want to know, is what sites can I go on to a) design a logo b) get shirts etc made with my logo. c) trademarking my brand
Also, are there any dropshipping places so that people pay me, and then the clothing gets sent out from their warehouse? thanks a lot! :)
