Give good advice
Your own craft probably has dozens of associations or oganisations where you can blog and share your skills. If you offer your skills in your particular area, it's a great way to reach new customers and show your leadership in your particular field.
Articles in the form of tips, best practices in how to achieve the results you have and writing on blogs is a great way to deliver your ideas.
Question and Answer sessions with people who want to know more will find you and appreciate your knowledge.
