There are likely a few ways to do this. Reaching out via your network for those individuals/organizations that can provide the input you need is an easy way and likely one you've already thought of. Another is to hire a connector, whose job it is to find these advisors for you. This person/organization could also determine which input is valid and worth considering versus what is fluff. Connections are also easier made when you have a broker of sorts finding them for you. I do a lot of that. Let me know if I can help!
