Posting on forums

I need a posting on the forums. These should be car forums. It should be a natural live communication in the forum, i.e. a comment is created to the main topic, and in the next message leave the necessary information - the prepared text together with the link.
After 5 days, if the message is not deleted by the moderators, send the link to me, I check and pay. Not only the message itself, but also the link in the message must be saved.
Payment is only on webmoney.
Offer a price for a post on 1 forum.
