I'm planning on starting a tutoring business in Northern California in
the fall, but I'm not sure exactly where to do it.  Here's what I'm
looking for:

*A place with lots of KIDS.  I intend to focus my services primarily
on the 7th-12th grade homework & test prep market, so I'm looking for
a rapidly expanding (likely suburban) area with lots of families that
have serious interest in the education of their adolescent- and
teen-age students.

*A place where parents can afford to pay $30-$50/hr for tutoring -
most likely an upper-middle class concentration.

*A place without a pre-existing hypercompetitive tutoring market.  A
few examples of such markets (it seems to me) include San Francisco,
Marin County, Santa Clara County.

*A place within 20 minutes of a Cal State or UC from which I can draw
tutors to train and place, OR a place with plentiful college graduates
looking for part-time work.

The geographic area I'm considering is Northern California and the
Central Coast.  I don't like LA, Orange County, San Diego or the
Inland Empire, so we're keeping it north of Fresno (except the coast).

Personal pluses for the location include:
*Access to open space / lakes / wilderness / greenery.
*A young adult / young professional population (I am 23/M UC Berkeley grad)

The answer I'm looking for is a specific town and/or county with
numbers proving that it is a growing, non-tapped market with a need
and ability to pay for private, in-home academic tutoring services.
