Costs for any project aren’t black and white, but having a general framework to approach the budgeting process will get you closer to an accurate estimate. Several factors will play a role in costs, and even just one change in scope can have a huge increase or decrease in budget. Bear in mind that it’s also important to find a designer you like and enjoy working with, and each designer will have his own rates, which will also greatly affect the end cost of your project.
Aloha Tatiana! I wish your questions had straightforward easy answers – and if you are government funded it kind of is. (See here: https://www.ada.gov/websites2_prnt.pdf) if you are not government funded, this is something that is currently being debated in the legal system. That being said, the WCAG 2.0 guidelines are a good set of guidelines to help protect yourself if you feel you should.

The fastest, most certain way to be sure your website is in compliance is to contact a qualified web design agency and have them perform an audit of all your online properties. Make sure you interview the agency thoroughly first, as not all agencies are up to speed on ADA website compliance rules. A qualified web design firm will be able to identify any violations of ADA Website Compliance and outline a plan for updating your online content and properties.
Talk to your web designer about other techniques that will make your site more user-friendly for people with disabilities. Worried that’s not in your budget? Consider the fact that DOJ fines start at $75,000. And it's still yet to be determined if a non-compliant website is liable for one fine or will be charge per page for each violation. As the recent lawsuits illustrate, though, settlements quickly add up into the millions.
