Product counter module?

I am in need of a counter on my site that will show customers how many items have been bought of each product. Is there a module that exists of this? Or is there someone that could create this for me? Thank you!

do search on extension, i think there is module that can do that. if you not satisfied, post an offer on commercial forum.
