You can promote yourself and all the services that you offer. You can share your experience and services by writing blogs
and articles about the services that you provide and also get involved in the same type of discussion.
Everything works if you know:
1) Your focused audience
2) How did they think on legal aspect?
3) What type of media they use
If you have a clear understanding on all the three aspects of marketing, you can get relevant and can select the ideal phase of media to reach your client with the appropriate message.
