Hello Dear, Greetings!
It seems you're looking for an Acrobat rockstar who can make 3 PDF file accessible and make it Americans with Disabilities Act (ADA) compliant. I can do the task perfectly as you desire.
I'm making PDF accessible to meet common accessibility standards like WCAG 2.0 and PDF/UA for the last 2 years. I have vast experience in making accessible PDF.
I will update all the image alt text, Title, Bookmarks, Readability and other common issues with accessibility. I will use Adobe Acrobat Pro DC to fix these issues. I will make your document ADA compliant. I know the logical structures and tags of PDF accessibility support so I know what I have to do to accomplish the project.
If you award the job to me, I can assure you that I will deliver you the best service out there. Kindly let me know your thoughts on my proposal. I would love to hear from you.
Thanks and Kind Regards,
Mehedi.
