Any experience with investment advisors for smaller portfolios?

Has anyone here had experience with an investment advisor firm ?

To be honest, I don’t really have the time anymore to actively research companies or keep up with stock volatility, and my performance hasn’t been great either.

I know ETFs are probably the safest option, but if there are alternatives with potentially higher returns, I’d be interested to hear about them.

I’ve heard of investment advisory firms, but they usually require hundred of thousands, or millions of euros.
