Marketing, Branding & Identity

I need a specific reply, not a 'shotgun' blast proposal. I would like some quick guidance on how to brand, market, and build an identity for an existing business that is taking on a new name, logo, image, etc.

I want someone with a marketing background to help me do this. I do not need a lot of time or information, but I do require some good ideas, maybe a Skype chat or good e-mail traffic to give me some SPECIFIC information. General info I can find on the internet for myself. I need a marketing professionals perspective. Once I have that I will move forward with all other aspects of the business. I have demographic data to share on my industry. I need an quick analysis of that data, and what I should do in response to those numbers - tell me what the numbers mean!
