Quick Question about UE4 Market

I want to design buildings in google sketchup and import it to Unreal Engine. Then, I want to sell the building asset on the market. How do I put something up on the market? Can someone please explain the process to me?

Top of page, click the menu Marketplace > Submission Guideline

I don’t know how well buildings will sell on the Marketplace though, you might want to start a [Gauging Interest] thread before you commit yourself.
