Add a GUI that allows you to sell plots from GUI, When a region is not owned by a player/does not have an owner it can be a tripwire hook or a lever(you can choose your item you want to add) and when it does have an owner/player linked to it it can be iron bars (again can be any item you choose). you should also let you confirm but I would let that be a config you can enable and disable. And then let's say you also bought the plot allow users to view a GUI that allows them to tp to a region, allow the owner to set a motd or a title for their region, I know this is a big suggestion and a little undetailed one but I have an image of how it should look but hard to explain how all should work.
