There is some good advice here, but in the end, this is all on you and not a financial planner. You can hire whoever you want, but out can't outsource the responsibility for growing this money.
Here is what I would recommend.
1) Put the money in cash (or short-term government) bonds for six months and use the time to educate yourself on finance and investments. Do not make any decisions until you feel comfortable you know enough to proceed.
2) Read the following books so that you can converse intelligently with potential financial planners and investment managers:
...a) Stocks for the Long Run - Jeremy Siegel (not an easy slog, but essential)
...b) Winning on Wall Street - Martin Zweig (probably an easier place to start)
...c) The Successful Investor - William O’Neil (also a good place to start)
...d) The Indomitable Investor - Steven Sears (for a broad, high-leve perspective)
3) Once you internalize this information, spend some time on the Vanguard web site, focus on ETFs, and give some thought as to how you might do this yourself, if you had the time and interest. (You can do the same with Schwab, Fidelity and TD Ameritrade if you wish.)
4) Ask friends and family for some recommendations for local Registered Investment Advisors and interview them. Talk to at least three. Compare and contrast what they say and how they wish to handle your account. Develop a BS-detector as you do this. Only consider RIAs that are compensated according to a % of assets they manage.
5) Give 25% of your assets to your two favorite RIAs and keep 50% for yourself. Watch and learn from their approach.
6) After one year, decide whether you want to give the additional 50% to one or both RIAs or continue to do it yourself.
7) Always keep reading and always keep learning.
Remember that no matter who you decide will manage your money, ultimately you have to be knowledgeable enough to ask the right questions and know when the answers are not what they should be. You may outsource the day-to-day decision-making regarding your investments, but you still own the responsibility for seeing that your investment objectives are met within the context of your risk tolerance.
