1) Offering your services on internet marketing forums. For example, the warrior forum.
2) Another thing you can do is take your forum service a step further and offer it on freelance sites such as odesk, elance, guru, and so on.
3) Fiverr SEO gigs
4) Offline clients. There are likely hundreds of local businesses in your area that need your services. Doing local SEO is typically a lot easier than doing it on a global scale, which is probably what you are doing for yourself right now.
