This was their response:
While Section 508 only applies to federal government websites, other accessibility rules may apply. Businesses must make their websites accessible if the business receives any federal funding or other assistance. Further, the Americans with Disabilities Act applies more generally to all businesses, and requires businesses to "communicate effectively" about their services. Under these rules, all businesses should make their websites accessible. It is good practice to comply with Section 508 rules regarding accessibility as that is likely where the rules are heading.
So the short answer is yes, you should make sure that your website is ADA compliant.

And if you're interested in hiring me to make your website ADA / Section 508 / WCAG2.0 compliant, I'd be happy to provide a free estimate.
This generally involves modifying the website's code so that it passes WCAG 2.0 compliance tests. Section 508 accessibility standards are usually discussed here as well, which directly apply to federal websites.
