Weblinkedin is great for having good search features and giving you the ability to connect the job posting with the company and any employees you can contact for a referral. Weblinkedin is the best tool for this, but good career long recruiters are not hard to find. It'll take a little bit of work on your end but research who a good one might be with at least few.

Weblinkedin for job in my field. I've changed jobs 3 times in 3 years and each one initiatally came through li. Indeed when looking for part time side jobs though havent found any.
