My question would be: why? What would a PM section accomplish that jobs.perl.org doesn't already? Only add a space for job offers without payment? Does the world really need another website for that purpose (given that job offers of this sort come for free in the mail and on a plethora of contracting sites)?
IMO what Skip or someone in a similar situation could do is put a link to the job offer (or even the offer itself) into their home node and put a short pointer at this in their .sig (e.g. "Looking for programmers, check my home node"). That should be unobtrusive enough to not be considered annoying by most monks and still give them the benefit of "advertising" in monk-space with every post they make.
Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -- Brian W. Kernighan
