Tip - How Can I Get Started With Online Marketing?

I've recently launched an architecture business with a colleague. My business partner doesn't know much about online marketing, and it's new to me too, but I've agreed to handle this side of the business (among other duties, of course). How can I get my feet wet with online marketing and start building a following for my business, with the goal of gaining customers?
