My question involves labor and employment law for all states:

I'm in the process of creating a website that allows small businesses to post and advertise their job applications for a lower cost than other job search websites. When businesses post an application, applicants will be able to fill out the applications on the website. Businesses will be able to see all the responses to their applications from their business profile. What kinds of legal grounds do I need to cover other than basic terms of service and privacy policy?
