Logo design

I am looking to have a graphic-based logo designed for my company. I do not have a color scheme in mind, so I am open to ideas that encapsulate the feel of the business. Additionally, I would like for a slogan to be included as well. The slogan should set the tone for the business, and also capture what we are all about. This logo will be used in all branding material, so it needs to be unique and stand out.
