Well, you would be talking about per diem work. The majority of per diem agencies pay per visit rates, at about $25 to $35 for a re-visit, and $50-65 for a new (3 hrs of paperwork).
To gross $550 a month, I am figuring on the $25 per visit rate, yu would need to work a min of 6 revisits a week. You don't say where you are located, but if it is in the SE, the pay for HH is very poor, worse than here in NJ.
There is a lot of improtant paperwork in HH, esp b/c if documentation is lacking in any way, remibursement for the agencu could really siffer. So, I wouldn't think they would let you get away w less than a two week orientation at 40 hrs a week, after that, I know my agency would take you for whatever you could give them, they do prefer a min of four hrs a day worked.
If you are paid per visit, you could do two visits go home and nurse, then do another two, but you would need to be assured the agency will keep you close enough to home to make that worth it. There are days when, as a per diem now, I am NOT close to home. One agency by me sends nurses to five counties, that is not d0-able for what you want.
You have 3 yrs nursing expereince, that is really good. You will have NO problem w adjusting to the clinical assessment, and will likely find less stress than having 8 pt at once. But, you will have to commit to understanding the paperwork. The regs change often, and it can be aggravating. Just don't take criticisms of the paperwork personally, the agency is under a LOT of pressure to get it right. Assure them you are a quick study and will read the regs on-line at home, ask for an OASIS guide, and promise if you are unsure of how to answer questions you will call in for guidance.
MY agency would take you in a heartbeat we are so short! Good luck.
