Chris - Have you tried with below plugin?
https://wordpress.org/plugins/auto-image-attributes-from-filename-with-bulk-updater/

Please do whatever so we can add the alt text to the images and if possible use a plugin that if we remove it in the future it will not remove the alt text. I am looking to do this one time and then remove 

Chris, 
Just watched your video. 
If Isaac can find a tool to do that, it would be awesome. 
However, I am worried that we may get the images flagged by Google if they contain similar or the same. 
I used unique and LONG TAIL Keywords in my images and I used to = still do - rank very well. 

Isaac - let's do a bulk update for now so we can launch the site, then Hector  you can go through and manually do it. 

Yes sir. I will begin going through them tomorrow morning. 

Isaac - nevermind Hector is going to manually do it. Here is a video

Thank you sir.
