Nursing staffing organizations in Florida, Maryland, DC?

Hi,

I'm a nurse practitioner/midwife looking for a job at a FQHC with a HPSA score of 14 or higher.

I'm trying to cast a wide net and found out that some states have nonprofit community organizations who maintain relationships with a lot of health centers. Job-seeking nurses send their CVs to these headhunters in order to get help being placed at various sites across their state or region.

I was wondering if anyone knows any specific nursing staffing organizations like this -- if you could link their website or e-mail address, I'd be very grateful. I'm especially interested in Florida, Washington, DC, and southern Maryland.

Thanks!
