to answer my own question...

so I called around and got an answer to my question. This is how it works. If you can get your doctor to write you a prescription for IV vitamin C therapy, then you have to get your doctor to call down to the company that you will hire the nurse from. They will take it from there.

But here's the punchline. Just for the nurses service that costs $250 per visit. Supplies cost about $75-$100. So that means you are looking at well over $300 per visit. that means If you have weekly treatments it is $300 per week

Sigh...
