In order to enter the ADA signage industry, you should determine if you are willing to put in some serious study time on what the goals of the ADA are, how accessible signage fits into those goals, and what details are going to be necessary for you to learn about and follow in order for you to provide truly accessible signs for your clients. Even if you plan to order the signs from others and resell them, you need to be able to distinguish between “good” and “substandard” signs if you are not going to put your clients at risk for lawsuits and complaints.
