Here are a few quick and dirty VTT maps that are compatible with Expeditions modules. The first two I made in about 20 minutes each, and don't have furnishings. I find it easier to just find the stuff I need in roll20, drag it in, and scale it there. Especially with things like chairs and beds, the character may want to move stuff around and if I put into the background image, that wouldn't work, visually.
