New York private practice - starting before PLLC is approved?

Hi folks! I am working on getting my own business up and running to have a part time private practice as an FNP and lactation counselor. Apparently New York State takes the longest to get a PLLC approved - 4-6 months basically! I forgot to take this into account in some of my other planning so I am wondering about ways to practice in some other format prior to the PLLC. I will of course be consulting professionals on this but if anyone has experience with this or information about starting to practice in NYS without/before having a PLLC I would appreciate your input!
