Some simple steps that have worked for me.
- Setup a website
- Use a professional e-mail addressl
- Create a linkedin profile
- Create a twitter profile
- Engage on twitter, linkedin and online communities like bytes.com.
- Reach out to other small shops and companies to see if you can help with any client work they have. This is great for referral work later on.
- Be patient
- Get a good accountant to help you with tax laws and financial planning.
- Be an active learner. Your clients needs will change over time so it's good to stay ahead of the curve.
I hope this help. Good luck in your journey.
