You will have to do some blogging no matter what, but you can check into things like eBay, woo commerce and other ways to set up an online store. There are those here that have done this but I forgot their names. Do a search above for online stores or woo commerce.

You don't necessarily need a blog if you have strong social media presence. However, I tend to think that the social media presence is bolstered by the blog rather than the other way round
