Take a look at artstorefronts.com. They provide over 10K artists with websites and tools to properly display and sell original art as well as prints, which is a great way to get expose and new purchases from existing customers. They provide a monthly marketing plan for you to follow which is basically a "playbook". They advise on social media, which is essential for your marketing, but you have to do that yourself. I found the organization for my son. He is attempting be do art full-time. I'll do all his marketing and technology things in the beginning, and gradually shift all of it over to him in time. It's a pretty steep set-up cost, which they will finance over several months, but the monthly hosting fee is $50. They earn 10 to15% of your sales, which incentivizes them to help you be success.
