I currently work a private duty case for Interim Healthcare. They are very competitive here in NY. I average $20 per hour as an LPN slightly sometimes more, sometimes slightly less depending on the kind of case I take on and whether I am doing staffing at the ALF. I think the pay spans $17-25 per hour for the LPN.
They accommodate me in terms of hours since I am having increasing difficulty landing a facility job, so chances are you could get full time hours and pay just through them. I do. Here is their website
www.interimhealthcare.com/northgeorgia for Atlanta. Good luck!
