This client is important #1 in Chicago. write the content yourself please. 

Some of it is original but quite a bit is duplicated text, mostly 100%
matches from at least four other websites. So unless those four other
websites are copying her then she has plagarized content.

Do what you think is best. She may have wrote it first and people copied.
Use what you can and create new content.

I think she got a lot from website. I'll use what I can and rewrite the rest
