There are so many ways to market your company online with LinkedIn, Twitter, YouTube and other social marketing engines. Definitely the forums are always helpful for ideas as well. I have found a great free business entrepreneur guide at www.innoventum.com which is 60 pages. This site also has a marketing product as well at: www.innoventum.com/bizmarketing.html that may be helpful as well.

Do you have a catchy logo and slogan that may attract customers as well? in the promotional product business I am sure that this may be key as well for people to remember you.
