HI, KP, and welcome.
Independent Contracting is no different than Agency A contracting with Agency XYZ to provide backup nursing staff. I have seen it occur, mostly in for-profit agencies due to cost factors.
My first agency worked as independent contractor to them getting $25.00 hr in 1985! I worked as much or as little as I wanted, paid my own taxes, malpractice; had husbands insurance, etc. Retirement Savings was in IRA plan. In return, I was last person called, often worked the evening cases, farthest cases from agency base that no one wanted--didn't mind though as kids young and worked when husband available. This agency's niche was being backup for ALL the infusion company's in my area so I might be seeing patients from 3 or 4 agency's with differing paperwork in one day: kept 7 agency's paper work in my car.
Yes, it is possible to do. Now, would recomend that you incorporate to protect yourself more from liabilities;own malpractice insurance
. MUST be prompt with paperwork--in within 48 hrs and properly bill agency; have excellent communication and followup skills. Be careful that you have guarantee for prompt payment from agency---can take up to 30 days to get paid.
Home fax, mobile phone, COMPANY car, beeper, etc----all CORPORATION business deductions. Might not get a lot of work at first, but as reputation grows should be kept busy,
