IMAGE MERGE and Prepare a catalog (URGENT)

Hello. I have a catalog which I prepared last year. I need to update it and add more people to it. I have all the information in EXCEL and Images downloaded as well. I need someone to run Mailmerge right away. I am using MAC so it's difficult for me to run it through as it keeps asking for file permission.

I need someone who has done mailmerge in the past and can do it right now.
