Hi,
Another option you have is start looking at creating a simple website, average expense should cost minimum $90 per month with the option to buy online.
As for a free starter, i would recommend Marketplace or Amazon best. You would be having a clear idea of the market offers and you would also be able to have your arts on a competitive rate.
There is the option of also using Alibaba or Wish but this might end up you paying part of the shipment, so not really recommendable for now.

Hope this helps a little.
