Need CREATIVE DESIGN for CUSTOM T-SHIRT & Clothing Company logo

CERTIFYED

I am starting an energetic clothing and accessory company callled CERTIFYED that makes custom tees, clothing and accessories. This clothing company is aimed at being unique, original, casual but sophisticated. The design should promote quality-- these are high end custom t-shirts.

Some brand logos, images, names and feel that I like are at:
http://www.sagaouterwear.com
http://www.jiberish.com
http://www.quiksilver.com
http://www.armadaskis.com
http://www.newschoolers.com
http://www.rvca.com
http://www.oakley.com

I am appealing to the freestyle skiier/ newschooler and snowboard market as well as other action sports enthusiasts. Whether you are on the slopes, cruising around on your skateboard or hanging out on the weekends, we want this brand to fit you and your lifestyle, a go for it attitude with an edge, but clean and simple, to stand out from the crowd.

I am looking for a logo with the brand name affiliated with it, although I'd like the logo and brand name to work separately as well. The logo/brand name should lend itself to being easily screen printed. It will appear on the label as well.

The logo should be clean and crisp, not too busy. It could be relevant to extreme mountain/ action sports culture, but not too specific.

As far as the brand name CERTIFYED, feel free to be creative with the letters. I may want a mix of upper and lower case letters, maybe even a backward letter incorporated into it. I like creative letter play. However, if you feel you have a great idea for a look, go for it. I'd like to see your thoughts as well.

Please keep designs in black and white. Make the deliverables in Adobe ILLUSTRATOR and PDF formats.

The logos should be easily recognizable and promote the retention of the Brand - a must have item. I do not necessarily want to see this pictured on a t-shirt--as it will be used for advertising, letterheads, and labeling as well.
