Situation Vacant Partnership in the process of buying and selling used agricultural machinery.

I am in Russia and sell agricultural machinery on Russian bulletin boards, like Avito, and at the same time create a website that sells it, but I do not want to be responsible to the client for the quality of a used harvester, tractor, Mulcher and so on! Are there people here who want me to send my clients to them for the process of concluding a deal on the purchase and sale of agricultural equipment (I plan to receive my salary in the form of a part of advertising expenses or as a percentage of the purchase and sale of equipment)? Can you organize the delivery of used equipment from Scandinavia, Europe, or the USA at a price that is favorable for a client in Russia? What guarantees can you provide to clients that they will not be deceived by you? Thank you for your attention to my post and I look forward to hearing from you!
