5% is pretty much for contract rate offset. But $100/hr is not an unusually large hourly rate right now for finance.

I'm curious what you want this person to do? If you're prepping for an angel or seed round, is there something unusually complex about your business that requires more than a proforma cashflow summary and a cap table? If not, seems like you're overspending for something that you can probably convince someone to do for you for free.

Try looking for an advisor who bangs that sort of thing out or already has one setup for a business like yours. For companies I've advised, it wasn't uncommon for us to spend 3-4 hours putting all that together one time. It's not brain surgery, and you'll be better off having learned how.
