Creating a free online store?

Hi, I sll youtube services currently only through ebay, but I want to open my own store online where I can sll these then I have a good link that I can do marketing with I want to also branch out into twitter things soon EG slling Twitter Accounts with 10k followers ect. So any tips on how to do this would be great I cant seem to find a good site that is free or doesn't take a "10 buck verification", Any help.
