Vanguard seems to offer advisors at a certain point -https://investor.vanguard.com/advice/financial-advisor but honestly I'm not sure what they can really provide beyond the standard bogleheads.
A separate advice session from a tax guy can be worthwhile but always remember that the tax guys work to minimize taxes, which isn't necessarily always the goal.
The bogleheads forum is great for general advice, even if you only read it: https://www.bogleheads.org
