Steve and Jane are correct. There are no free lunches unless you are completely self-directed and buy no-load funds, etc.
There are numerous ways to hire a qualified professional advisor. Qualified, which usually means licensed, a member of a professional association, etc. You also need to check their records to be sure there have been no disciplinary actions taken against them (see links below).
As far as fees or commissions, some advisors are paid a one-time flat fee for a comprehensive plan, some assess an annual fee, some work on a percentage of assets under management, some work on straight commission from the investments they place your assets in.
As I have posted earlier, there are several websites to research, but the best in my opinion is:
http://www.cfp.net/ Click on the learn about financial planning tab for more information. Other good sources are Jonathan Clements, a contributor to the Wall St. Journal at:

http://www.dolans.com/. They also have a syndicated radio show that I listen to religiously.
