Conditional Formatting on expiration dates.

Hello...

I have a spreadsheet where we track our contractor's Worker's Comp and General Liability insurance certificate expiration dates. I want the expiration date to highlight in red if it is expired and to highlight in orange if it will expire within 30 days or less.

I have attached a testing sheet similar to what I'm working on. The F column has the dates that need to highlight. Please help! Oh, and I have MS Excel 2010. Thanks for any help you can offer!
