I've seen plugins such as SimpleRegionMarket, but I would like a plugin that not just sells regions, but areas inside regions. For example, I have a city protected by WorldGuard. People cannot build or break blocks in it because of WorldGuard. There are plots of land in the city. I would like a plugin that makes a sign, which people can click on, and if they have enough money, it creates basically a Sub-Region within the WorldGuard region that only the person who bought it can build in. (Obviously with a config file that lets me choose what they can do in the sub-regions). Thanks.
