Macro for Protecting Sheet (with same name) on multiple files at once?

Hello Excel Geniuses!

I have received so much help from this community I hope someone can help me with this request.
I have a macro that duplicates a excel file into how ever many files I need... so If I need 150 copies of the the file, it will make it 150 times.

However, each file the first tab called "Clients" has information that I want protected so users can't alter it.
I can't protect it before I run the duplication because the data is added by a group of people and I need it unprotected until they add the information.

What I am looking for is a macro that I can click and run, allows me to select multiple files, then it will automatically Protect Sheet 1 "Clients" on all the files I select so I don't have to open all 150 files after data is entered and Protect sheet 1 manually.

Anyone know how to do something like this?
I would greatly appreciate your help!!!
