Now, I have a question about this...  Is the customer using the sites 
for redundancy, and will have both upstream providers in each site?

Honestly, a small operation like this may be better served by multiple 
connections to the same provider.  Such a setup can usually be done to 
multiple routers, through redundant circuit paths, and done at 
substantially less cost that two different providers.  And, in my 
experience, using one provider can often be more reliable than multiple 
providers, given how many providers transport facilities ride the same 
fiber path, and sometimes the same bundle.
