Looking for a PostgreSQL Expert/Master in the Baltimore/Washington Area

Hi,

I have a client in the Baltimore/Washington area that could use some
consulting from a PostgreSQL Expert/Master. They are using PostgreSQL now,
but it's not scaling the way they expected. They need someone to review
their approach and recommend a path to better performance.

Do you know of anyone in the Baltimore/Washington area that does consulting
and qualifies as a bonafide PostgreSQL Expert/Master?

 Thanks!
John
