Mark,

It largely depends on the customer. We prefer delivering a manual test
assisted by automation tools. You can't really provide value with 100%
automated anything because artificial intelligence is artificial.

On the billing question; do you trust your estimation abilities enough
to go fixed price or do you charge by the hour? That too is an
individual customer by customer judgment call. If you ask enough
probing questions ahead of time you should have a reasonable estimate of
the time commitment involved in performing the work.

Jerimiah Grossman gave a talk on the Challenges of Automated Web
Application Scanning last week at the Black Hat federal show. His talk
is worth a look over.

Which is why conversations like these are helpful. Even more helpful is
technical level feedback. On the technical front, please check out the
OSSTMM (http://www.osstmm.org) and OWASP (http://www.owasp.org) projects
and consider contributing where possible.
