Sponosred Produckts In List Cathegory

I'm looking for an add on that would make more advertisment space in multivendor .
vendors wuold also have an opportunity to have a better promotions of their produckts. that would be a payid option as sponsored link.
when client goes to some cathegory it has now this view:

it would be nice to add (paid) sponosored produckts that stays always on the top so the costumear will always see it by entering the cathegory or even serche keywords:

those two first are payed and visible by enterign laptops/apple
it would be even bettter if there wold be an option to promote produckt in regular listing but with diffirent back ground so it stand outs forme regular list and costumear notices it :

thank you,
