I am looking for an indexed version of the yellow page data that I can
import into a database and use in a mapping program.  The data should
be categorized relative to the categories of a standard printed yellow
pages directory and should contain address, name and phone number of
the business.

Cost is definately part of the equation, we are not looking to spend
10's of thousands of dollars for this service annualy.  An affiliate
program where we need to link the display back top the data source is
a feasible solution as well

I have already looked into info-usa and Faust Information but am
looking for more alternatives - thank you
