Starting an accounting firm - need advice

I've been tasked with starting an accounting/bookkeeping unit for our company and I need to start drinking through a firehose because I'm out of my depth.

Unfortunately, my linkedin and real life network has hardly any overlap for informational interviews.

Things like processes, tech stack, hiring, legal, etc...

If anyone is in the same position or has been through this, I'd love to have a phone call/zoom.
