Mention ADA compliance to many web developers and you may encounter a blank stare. First, find an agency working with the web platform or framework you use and ask about how their development workflow addresses accessibility. Most platforms have a partner directory. From there, you can start vetting agencies for their actual experience with web accessibility.
How much their services cost. One of the most important things to determine is how much you’re willing to spend on a website, and then take note of how much each agency charges. The sentiment holds true that you typically get what you pay for — if a web design agency is charging dirt cheap for a design, you probably won’t be happy with the results. There is definitely room to have a budget, but keep in mind what you’ll generally need to pay for a high-quality website.
