In a few sentences, explain who you are, what you do, and the benefits of your product/service.
Consider attributes that you'd you like your logo to reflect. Key words can be helpful: are you environmental and urban? Technological and futuristic? Be thorough.
Names and website links would be helpful. Also, what makes your company unique? Do you provide different/better services and products?
Website? Stationary? Brochures? T-shirts? Billboards?
Gender, age range, income level, location, education, etc. This doesn't mean this is the only type of person you market toward, just the primary type.
Other logo designs you like (or don't like) or any designs of any kind that you think have the right tone would be helpful.
