Auction feature / plugin

Is there a plugin (official or custom built) that incorporates an auction feature on Discourse? Where users can auction something using a topic where they can, for example, set things like the starting bid, price increments per bid, and maybe a buy it now feature (kind of like eBay, I guess).

If I use the search, I end up in this topic: Auction feature, which points to this topic: https://meta.discourse.org/t/buy-sell-category/15655, which no longer seems to exist.

Also, if more people are looking for this feature (and it does not exist yet), maybe we can pool some money together and get it built.
