If you're talking about tax preparation help, you want a CPA. Generally, I'd suggest starting by asking your coworkers and perhaps your manager if they have a CPA they'd recommend. Friends in a vaguely similar financial situation are also a good source for recommendations.

A good number of CPAs also provide financial planning services. You could try looking for a CPA that is also a CFP or a CPA with the FPS credential.

If you don't really need or want help with tax preparation, I would just find a fee-only CFP.

The financial advisors wiki article has more advice.

I'd also suggest checking the PF wiki to start your own education. There are a lot of articles to read, but the Prime Directive is a good place to get started.
