Best Case Scenario: 3 Months
I submit work to a gallery, they review it within 4 weeks, the love it, and ask me to show. They don't have anything lined up for next month so I'm their guy. The show stays up for a month, all of my artwork sells, there aren't any billing issues, and the gallery cuts me a check. 3 months...
Worst Case Scenario: 8 Months / Forever
I submit my work. The gallery might not even respond. If they do, 6-8 weeks before I hear back is common. If they run their business well, they'll have shows lined up at least a few months in advance. Let's say they like my work, it gets hung. A few paintings sell, but there are billing delays (there are always billing delays). I finally get a check 7 or 8 months from now. And that's IF they like my work.
The gallery system is slow. What to do about this?
