Hi,
We're needing a logo for our starting company. The name of the company is GreenKidz and what we do is prepare, package and distribute organic, healthly food for children.

What we're looking for is a clean yet still fun logo for our company. Nothing too "kiddy" as our target children age is 7-13, yet we definitely want it to come across as cool that parents would wear a shirt boasting the logo.

We're thinking besides a word play, some sort of symbol or character that could stand on it's on and start to establish branding without the GreenKidz words chasing it around.
We're pretty much open to everything, but obviously green is necessary in the color palette. We would also like the VERY minor use of another brighter color, ex: orange that can be properly used as an accent color in our marketing material and website.
Take the reigns on this one all, and will be leaving feedback daily to try and target what we're looking for.

Our current logo can be seen at http://www.greenkidz.org

And if you have any questions, please don't hesitate to shoot me and email.
Good Luck!
