We're not looking for anything psychedelic or cartoonish. Rather, we would like it to come off as natural, healthy, and organic while at the same time being in-style. The leaves in our name imply salad lettuces while loaves imply sandwich breads. Incorporating this into the logo would be a plus. Please no tacky clipart.
Keep in mind that the logo you are being asked to create will serve as our new identity and we will be doing business under it. You must visualize it on everything from a huge facade sign hanging outdoors to advertisements to menu boards. You are free to experiment with the color palette, although keep in mind we will be incorporating it in all of our business material. It should be easy on the eyes while conveying our message in a warm, refreshing way. That's not to say it can't have a hint of boldness.
Please be ready to provide all source and vector files which you create. The logo will primarily be used on print material, so it must be compatible with accepted standards of most printing and sign making companies. I must have everything I need to have said materials created. This means all vector and pixel files, including: .ai CMYK files and original layered .psd files. I will also need the web and PMS color codes for all colors used. The logo will be trademarked and must not be infringing in any way.
To put you in the right direction, please think something along the lines of a fusion between Panera Bread (http://www.panerabread.com/) and Whole Foods (http://www.wholefoodsmarket.com/)
