If contract work isn't against the rules for them (not sure), and the job is otherwise reasonable (feasible, not too open ended, not throwing up giant red flags) I bet he would get some bites by posting to the monthly "who is hiring" threads too.

Depending on the details of the request I might be willing to do it, more because I think it might be interesting to work on a "farm equipment control system" than anything else. Coincidentally I gave notice at my job a week ago so I'll have some free time coming up.
