Design a Logo

I need a logo designed. The name of the brand is "Brenny Bear" or probably "brenny bear". The target audience is kids between 4yrs - 15yrs. The challenge will be creating something that is cool and cute but not too 'young', and that will also appeal to the teenagers, and to boys or girls equally. Maybe a bear wearing sunglasses to make him a cool choice. A simple one dimensional, one colour logo is good. This brand will be printed on various products.
