This is the company that I used as a single practicioner and as an agency serving the community. You may of course, you whomever you like.
Notes regarding required insurance:
Liability Insurance (1 million minimum)
Privacy Insurance (50 thousand per occurrence minimum) --- (If you get liability insurance with the company above, privacy insurance is included, if you need standalone privacy insurance you can email: Kelsey.firstname.lastname@example.org - it does not have to be from this company)
