We've got gutter guards, too, and haven't ever had to clean our gutters. So, it might be worth thinking about. Don't waste your money on the little screens and things -- I had those on my old house they didn't work at all.
One note: I know this goes without saying, but be careful when hiring "just some guy" who cleans gutters. It's worth the $$ to get someone who's insured and ask to see their worker's comp policy (or have them sign a waiver, which actually doesn't cover you 100%, but would help if they tried to sue you). I have a friend who got sued by someone she hired to paint the eaves/fascia on her house -- climbing on a ladder and reaching to clean is definitely something I wouldn't want someone to do that wasn't insured. Mowing grass, sure. Minor repairs, sure. Climbing on ladders, no way.
Just my two cents....
