This presumably is how you keep fit: jumping down people's throat, leaping to conclusions, running around a pile of non existant second hand wrought iron fencing, and all the while eating a jar full of peanuts.I think it is quite obvious what they are wanting.
They want a non-professional welder to go to their property, supply all the tools of a professional welder, do the job of a professional welder, turn a pile of second hand wrought iron into a fence and all in exchange for half a jar of peanuts and the satisfaction of having done a favour for a random stranger on the internet.
