I hate to say this, but if you are paying someone to drag it out of the woods just to sell it, I would recommend that you skip a step. Don't bring it to your yard, just go right to the scrapyard, while you have it on the trailer. I don't know what you gave for it, but you probably will have more in the hauling than what it will bring, IF you can get someone to buy it.
There's a lot of them still out there, from county or state highway departments, and old bridge construction companies, that run and drive and everything works, and are still in pretty good shape. And those won't usually bring very much money. To try to get someone to out out cash $$ for a project from the weeds- there's just no buyers. Sorry. I like old iron as much as anyone else, but there's just very little value there.
I think if you unload it in your yard, you'll just end up paying someone else to haul it away later. And again, I'm sorry, but I think that's realistic from the pictures you've posted.
