Before my aborted retirement in 2019, I started to build a relationship with a FA for exactly those reasons. He invested several hours meeting with me to understand my investing style, he analyzed my portfolio, he knew I was not interested in putting AUM. At our last meeting, we agreed that he would give me a quote for an ongoing advisory relationship of perhaps 4 quarterly one-hour meetings in the first year of retirement, and as-needed after that. He could propose new ideas or point out things I was neglecting, and I would gladly listen.
Then he ghosted me and I never heard from him again. I let his firm know that and they didn't seem to care.
That's the heart of the problem, lots of folks might be willing to pay a few thousand per year for expertise on a fee for service basis.
But that's not where the money is for the industry. Ultimately AUM fees can add up to tens of thousands of $/year for a couple hours of their time, a much better return on invested time for the FA.
