Unfortunately, my overall experience has been that hiring any “expert” in a field that I am not also an expert in has a 50% chance of working, and a 50% chance of blowing up in my face and creating more problems.
I recently attempted to get a new accountant to help me handle some business growth. It was a person from a well regarded local firm, initial meetings were good, and then they proceeded to deliver none of the agreed-upon work, take 2-3 weeks to respond to emails (multiple times, I had to call their office and schedule an in-person meeting just to get a response), and then de-prioritize my business relative to other clients so badly that I wasn’t able to submit my taxes until June.
If anyone can successfully build a service that lets me reliably pick professional-services providers with the same level of confidence that I pick an AirBnb (not 100%, but pretty good, with an expectation for reasonable mediation and fallback coverage if the offering is radically different than what’s described), I would happily pay a 20% premium on those services versus the existing “ask friends for referrals and cross your fingers” status quo.
