Ideally, you should be paying them for their time, and they shouldn't be getting any commissions other than you paying for their time. Look for a "fee-only advisor" who has a license that lists them as a fiduciary, which means they have a legal obligation to act in your best interests.

But honestly, you probably don't need one. Personal finance is relatively simple:

• keep 3-6 months cash in an emergency fund
• pay off high interest debt - where high interest is usually something >6% or so
• invest in low-cost index funds - if you're unsure, find a target date retirement fund with fees <0.20% (anything up to 0.50% is still "low" though)

But if you're not confident, find a fee-only fiduciary advisor to educate you about investing. A good one will help you feel more confident and provide options, they won't be pressuring you into any particular decision.
