We have been undergoing a "world of work" with our new forums and all but there is a likely possibility we will soon have a classified section that is more like actual on-line classifieds (ad categories, ads with descriptions & full text & photos etc. not just a forum like we have now, similar to this one).
If we do get that implemented such a section could be created but like Robert here we don't really think it's fair for dealers to get free advertising.
Our current dilemma is (a) offer free classifieds in a more advanced system, still no dealers (b) spend more money we don't have (we're still trying to get donations to pay for the new forums) to get classified ad software that would let us make a difference in free and "paid" ads. That type software is GREAT but it's not free or even cheap. But we have looked at ideas and are continuing to do so. (c) do option '"a" and make a section like you describe but then spend hours trying to verify the "deal is real" even though the ads are free.
Even for the paid ads we couldn't charge much but it would keep some dealers from flooding the place with free advertising under the guise of a closeout item or whatever. So it's kind-of a hard deal. We imagine Robert would face the same dilemma, how to tell an honest dealer with 3 "leftover" 2004 Graco 3900s from a dealer just calling them that when they sell them that way everyday and have a warehouse full?
There is a magazine for example called PaverMarket. The deal is supposed to be dealers buy regular ads at a per issue rate but individuals can run 4 "classified" type ads for $100 for a whole year or until the items sell. However if you ever see the magazine you will see many "personal" ads for a variety of equipment not likely any one contractor would own (or they would have a really weird business) all with the same name & number so you know it's dealers posting as individuals to get the cheap advertising. Sometimes they are so bold as to run an ad picture with a "line" of different equipment behind it or a "dealer looking" building in the background of several ads so it's pretty obvious.
