I Need Free Templates for Company Catalogs

Please I am looking for a reliable resource where I can get these kind of company brochure templates to download for free

https://designshack.net/articles/inspiration/70-modern-corporate-brochure-templates/

I wonder why these are so difficult to find. I can find premium wordpress themes which are far more expensive. I can find very expensive software so i know there are places i can download these. any tips?

thanks in advance
