We have a very simple contract we use with our clients.  It sets out our prices, conditions for additional charges, and terms of payment.  It is less than a page long.  If a client does not like our conditions, we just don't work with them.  I don't feel these national vendors really care about the local examiner, they seem to be interested in turn times and prices only, not in the quality of the work.  I know things are different in other areas of the country, but I am much happier here working with local clients.
