we sourced all our candidates through https://lispjobs.wordpress.com . Given hard requirement of relocation to Australia Adelaide that was very efficient and pleasant experience.
We also tried recruiters and stackoverflow. One recruiter was very good at selling himself to upper management and was pushing unqualified engineers into our throats. Stackoverflow was less targeted than lispjobs blog, but much better than typical recruitment company.
lispjobs was so good that another our practice of flying candidates in to spend a week of hacking together after brief phone screen wasn't that expensive at all.
