ADA Compliance for Joomla site

A existing Joomla site (V3.7) needs ADA compliance. The template has few errors (alt text missing, missing label, empty links) that need fixing and some other adjustments to existing h1 tags, alt tags so they comply to ADA. The job is fairly simple and for someone conversant with Joomla and ADA can handle this easily. People who can do it only apply. This is a urgent project so read and question the requirement if you need before bidding but don't put quotes without understanding.
