Set up a shopify and accept bitcoin via selling stuff. Very easy to use, very low cost and no technical skill needed. Just be careful what you sell, keep it legal
Shopify or a woocommerce shop with the bitcoin payment gateway plugin are the most easy and cheap ways to get yourself a webshop.
But remember from there the cheap starts. Because when you are in the marketing fase you will have to spend money, if you want to make it a a success.
I don't like the shopify system, because you depend on a third party. That's why I would advice to set up a joomla or prestashop installation and get the apprioate bitcoin payment plugins.
In just a matter of hours you will have your webshop.
I like Bitify and open bazaar. They are both p2p and there is no need of a third party. what do you think guys?
