US-JPY Financial Advisor, upfront cost 3500 USD, worth it?

As title suggests, I have found a specialized financial advisor who does management and an upfront cost of 3500 USD. I have a moderately complex situation as a company owner in Japan with US citizenship and am wondering if this is worth the holistic approach (his services specialize in U.S./International financial planning) is worth it. I see the benefit and risk prevention (getting his advise to get the most out of my investment strategy and help build that strategy) but am wondering if doing my own research could save me more money.

Any tips/thoughts I could ask japanfinance?
