Ballpark figure–$1000. Often, that is for the first year and subsequent years of working with the same advisor are much less–on the order of $300.
Yes, I have a financial advisor. After 20 years of doing it on my own (and doing a good job of it, I might add), I decided to get a second opinion to adjust my investments and to review such things as life insurance, retirement planning, and college savings for kids.
You should use a certified financial planner with a firm that you trust. Most of the big investment companies–Vanguard, Fidelity, USAA, and others have a separate financial advisory service. Only get a “fee for service” financial planner. That means that you are paying a flat fee and the fee is not tied to investments you make or life insurance you buy. A “fee for service” financial advisor will give you disinterested advice. Mine will tell me about financial products offered by his investment company and those offered by other companies. I can choose to buy from that investment company or another.
Finally, remember that whoever you use is an advisor and you are free to accept or reject his advice. My advisor has talked about products (such as annuities) that I am not interested in. I tell him that and he suggests other options until I find what I prefer.
