Management Consulting - How Can I Start?

I want to start a consulting firm specializing in developing corporate strategic solutions to assist organizations operate more efficiently and boost their annual returns. I know of all the logistics involved with regards to company registration and all that: what I need to find out is the best step to take in getting my service known and appreciated by organizations and small businesses, as well as develop a strong online presence. Family and friends are not an option in this case. The internet has so much information that I am now feeling overwhemed by it all. - Any experienced marketers and advertizers out there who can give me a step-to-step guide? Thanks!
