Hi Dana,
Thanks for the reply! You are correct in that I'm not directly employed by these clients. I'm guessing our best option would just be using a similar base, and reworking the content enough as to differentiate.
The difficult part comes when all the locations will offer the same services. We'll just be tasked with coming up with new ways to say the same things. Home/About Us wouldn't be tricky because that makes unique content creation a bit easier.
Thank you for your quick reply!
