Online Farmer's Market?

Hello I don’t know much about farming, but I read that farmers don’t make as much as people think. So I thought it’d be smart to start an online farmer’s market for farmers to sell directly to people without retailers & wholesalers (i was thinking this would give the farmer more profit for his/her work). They’ll grow, and I’ll deliver the orders. Customers would be getting high quality produce for, what I hope will be, at a lower price than grocery stores. Is this possible? And is it even legal?
