Go to any meetups or conferences you can find for tech stuff. You'll probably find plenty of recruiters, or at least people who can introduce you to some. I've got pile of recruiters messaging me on LinkedIn, and they almost all explicitly ask if I can point them at any other candidates who are looking. Bring business cards with your email, phone, and website, even if you have to get them made yourself.
In my experience, doing any of this even half-heatedly is plenty to get you so many recruiters that you'll start wondering how to get them to leave you alone after you take a job.
