Welcome to the forums keith.
Although certificates are a great thing and something which will help you surely, consider that experience may be more important. I know some people with some well-known certificates which seem not to know really much when you start a discussion with them. Others I know have only a few or no certificates and are "high-skilled" penetration testers.
I would go for one of the certificates in the penetration testing management area which may help you more in terms of getting new clients.
