I'm a painter and do mostly landscapes. I started with oils but switched to acrylics because of the fumes of solvents. I'm represented in a small gallery but i also have an online store on my web site. My goal is to keep the larger paintings for the gallery and sell my smaller works on paper online. My gallery is ok with that but i don't know how to promote it. I have a professional Fb page and i'm on Instagram. I have great comments but i've not been posting regularly so my audience is growing slowly.
I have a wife, two teens and a day job, 4 days a week. I'm looking for tips to jump start my online sales.
First, i simply want to reduce my day job to 2-3 days a week. Eventually, i'd like to quit it.
