Don,
Being the savvy internet marketer you are, I'm sure
you have already checked Google "images".
A search for Chiropractors or Pest Control
at Google images returns many photos.
The thing to check is the "availability", i.e,
are they royalty-free or do you have to pay
for usage. But if you are building a commercial
site, you just add the cost of the pix to the
final price of the package...
Be blessed,
