I never try to sell single maps, usually there would be multiple levels, so an inn might have main floor, upstairs guest rooms and cellar, perhaps an exterior barn and stable as well - I try to provide lots of content then try offer it for a fairly low price. If you ask too much, you don't get many sales. Consider my 100 map object set for $10.99, I don't sell many of that set, however the smaller 50 object $4.99 set sells quite well. I don't have an exact formula for charging for map products, but in my experience, selling items for an average of $5.00 is a good place to start.
I've got a Kaidan product that has a written mini-adventure, some new haunts, a curse and a unique ghost template, otherwise the product is a room by room gazetteer of a five story Japanese bath house, and sliced maps at 1 inch = 5 foot scale, 9 pieces per level - so 45 pages of sliced hand-drawn maps. I sell this product for only $4.99 as well. Consider this a detailed map product with some game mechanics as well - something that a cartographer alone cannot normally provide, but I still don't sell all that for more than $5.
I suggest you look at Jonathan Roberts who has some map products for sale as well.
