With EveryArt (YC W12) you don't have to be afraid of commissioning art 
I come from a family of artists so I've always hoped that we day see a world where most regular people to have nice art on their walls, at home and at work. At $1000/piece that idea is still out of reach for most people, but it's a good start.Interestingly enough, I think you could learn a lot from tattoos. Millions of people get tattoos because it's a way to express themselves in a meaningful and unique way for a couple hundred dollars. If you can make art culture something more personal and approachable, like tattoo culture, you may unlock a huge market and make the world more beautiful to boot.
