Getting a CPA really only pays off if you have your own business. As an individual taxpayer, there is only so much you can do to minimize your tax bill. Most of the solutions are in turbotax and can be discovered via a google search.
Where a CPA comes into play is when you 1) own your own business, 2) assets reach 7 figures, &/or 3) you have a complex estate plan (trusts/variable life insurance). If two out of the 3 are correct, then you should use a CPA in some shape or form to help figure out how to organize your business life. Otherwise, it's tough to justify the costs.
For investments, it's tough to get someone to give up their time to speak about buying/selling securities unless you have a decent asset base invested with them. It's just not profitable for them. If you are investing under six figures, I would suggest low cost index funds until you find an advisor who fits your investment philosophy/risk profile. This way they'll have to make an argument for the value of their services vs. simple indexing at a low cost complex (Vanguard, fidelity).
