Where's the flipping money?
I'll take a horrible job for $$$, a moderate job for $$ and a brilliant job for $: so would most people.
However, last time I looked at the contractor market I was offered day rates significantly below what I make as a permie.
Recruiters: if you want a smaller number of people to do what would ordinarily be the work of a larger team, plan to spend 80-90% of what you'd need for the full team. Less than that and your small number of people will create an even bigger problem, very quickly indeed.
