I found them by searching these forums and reading, reading, reading. Highway hypodermics.com has a huge list of travel companies. You can find OA at oanursetravel.com. PPR is ppralliedhealth.com. The recuiters I talked with seemed really nice, but they didn't have a lot of jobs in areas I wanted to go right now(don't want the southeast in the summer), or the pay wasn't acceptable. The best luck as far as assignment choice and pay is with Foundation and Abetta. Good Luck, and wish me luck!
