Profit by Giving Your Fees Away

I saw this little blurb on the Church Marketing Sucks blog:  

WaterFront Community Church says, “We’re going to give away 100% of our offering to help build and beautify our community.”

What would the impact be if your firm did the same thing, and donated one day's fees a year (or month) to make your community better? 

I think it is a great idea -- and could be even better if combined with a contest (like Pepsi's Refresh Project) that sought entries from school children or community groups.  What do you think?
