Word of Mouth

Sorry to be rude but how can you launch a marketing company when you yourself don't know how to market and asking other people?

For one thing you need to think about the people you want to target for example, it's all very well using sites like Craig's List but think about the people that use them and how much money would spend. Put yourself in the mindset of your target client, where are they and how do you reach them.

Lilach, you made me laugh. Well said!

Marketing: To convey value.

To me that means that you need to get out and convey the value of your services to people who would want them. Should you pay for advertising? Not if you are asking that question.
First of all you will need to find these people. Where do they hang out? If you don't know where your ideal customer hangs out. You will be wasting a ton of cash on what I call feeler advertising. I would search the forum for an ideal customers list. The things to look for and how to pick your ideal client.

Jay-Z knew nothing about clothing before he built and sold Roc-A-Wear for $280 million. Chris Sacca didn't know how to write a single line of code, and now is the largest individual shareholder in Twitter. I started as a lead generator in a given vertical 7 years ago, and now I guest write for the leading sites / blogs and get calls each week for folks asking for my "expertise."

I could go on... The list goes on. If you have the drive and most importantly the "I am going to do this" sort of tunnel vision you can teach yourself this stuff.

Identify your core skill. What is it that you are really really good at? Build products around that and exploit that. I love to write, and average about $5 per word - minimum job $1k. I'm writing video scripts, e-mail campaigns, voice broadcast greetings, and direct mail pieces. I'm outsourcing everything else. SEO, design, video production, etc.

Video is exploding. Become a video SEO master. Charge a crapton for that core product / service and run thinner margins on the other products.

Lastly, I've done well to create a "packaged" solutions. In other words, no one can just buy one service from me without buying the other.
