DON'T go to a financial adviser who makes their money off of your investments. They have every reason to steer you into investments that help them more than they help you. DO go to an independent, fiduciary adviser who will charge you a flat fee for their advice--the advice is pure because they have no stake in your choices. You do lay out a little cash, but everything is in your best interests, so you'll more than make it up in investment returns and lower fees. You likely will be better off choosing a passively-managed mutual fund. You won't have to make any decisions about the investments, and the fees are low.
Ask if they can help you with or recommend someone to help you with the tax returns. That's not an insurmountable problem, but it would be better, and cheaper, to get it taken care of sooner rather than later.
