Your current line of products and the Kickstarter idea look promising, but yeah... you want the style and quality of either Jared Blando or Franscesca Berald (?), you want it within a month, and you want it for a price that I'd probably charge for a rather simple, top down color town map without the elaborate ornaments. For a private client, that is. Looking at all the talented pros and semi-pros here, unless (as Tiana correctly stated) a very dedicated new artists takes this, you're looking at a price tag in the high three figures/low four figures range. Still, best of luck to you as the setting seems really cool.
