A very good point is made in this article. "Understand that value is more important than cost" or as someone, somewhere once said "price is only an issue in absence of value".
That's true about the price/fee you pay for anything. Haircuts, car washes, home renovators to your finances....ie whatever service you choose to use in life. 
If you don't find value in paying someone and think you can do it yourself, go for it. (I tried cutting my own hair once so I wouldn't have to pay the barber...disaster.)

The list at the bottom of this article is a pretty good start to assessing that for yourself.
I use a financial advisor and I feel I got my money's worth. Good advice, great performance (crushed any etf/index funds") and terrific service.
