I would make plans to tackle these 4 areas. I think you can do most of it yourself if you want.
1. Identifying and maximizing ways to save for day to day things - housing, food, transportation, etc. Ways to increase income (assets versus liabilities). Identifying financial goals (i.e. FIRE, house, etc.)
This is good link for some thinking:

2. Reducing taxes - This will be tough as a single filer. Buying houses and other things for the tax deduction don't always make sense financially. If you don't want to do the research yourself a CPA might be good to consult.
3. Investing the surplus. The Boggleheads books are a good start here if you want to not think about investing much and get good returns on your money. If you want to be more involved and take on more risk then I would read up on Finance or hire a fee-based financial consultant for this. Hiring a professional here is not necessary IMO and the Bogglehead books shows how it may actually hurt your returns.
4. Legal stuff - Protect your assets with proper insurance. Set up and wills or trusts that may be needed. I'm assuming you don't have dependents but still a good one to think about and have. You can hire an insurance agent or attorney if you need help in things here. If you don't yet have a lot in assets or dependents you may decide you don't need much help here.
