Find me a buyer for a huge amount of car parts and get a commission on the deal

I need someone to find me a buyer for a huge amount of car parts for European car mostly but not entirely (manufactured between 1985 and 2005 but not entirely, there are parts for newer models also). The one freelancer who finds me a buyer, gets commission after the deal is done. Milestone process would be used. More details would be given to everyone in PM when applied.
