Owners and aspiring owners - where are you going find and evaluate financial/professional resources?

I'm curious to know where you're going today to find options for legal, accounting, lending, insurance, software, financial planning etc resources and then also how you're evaluating the options you find?

Are you getting most of your guidance from this sub? Referrals? FB groups? Other forums?

I'm especially curious to hear from those of you involved in or considering private practice ownership.

Are there areas where you are feeling especially well resourced? Areas where you feel there is a noticeable gap in information availability or quality of options?
