So somehow along my career I fell into accessibility dev for a while. Funny enough it was one of the most lucrative dev jobs I did and there was always plenty of work. It is easily outsourced to a remote developer because all you really need is a browser and a screen reader. In my opinion there really is no reason for even mom and pop sites to not provide even a base level of accessibility, it really is just setting tab indexes in correct order, as well as making sure items have alt and title tags so that the readers can pick them up and actively describe the page. No I am not saying that this provides a great experience for the blind but it at least helps them to be able to get around the site.
I personally an color blind, which is not a disability but it is a pain in the ass at times, especially give that color has the ability to convey data visualization in a rapid manner that is subconsciously parsed by the user. It's extremity effective if one can see color. It is kind of how I got into accessibility for a time. By simple adding a secondary reference of iconography for the color blind a site can convey the same info. (e.g if you show red put a small stop sign on it, yellow use a triangle etc.)
I see no reason why even the smallest sites should not be able to provide access to the blind, whereas larger sites should be striving to go the extra mile to make it accessible and easy to parse for everyone.
