Here's some web sites where basic legal research can be done to find cases to help your client for free or near-free.
www.Casemaker.us is available as a benefit for many state bar association memberships, but if you aren't a member, there are some other sources to tap. Everyone has their own preference but here's some to take a look at:
www.Findacase.com
www.lawguru.com
www.Findlaw.com
www.precydent.com
www.lexisone.com
www.plol.org , the Public Library of Law
www.altlaw.org
www.justia.com
www.megalaw.com
There are others out there, but if your budget doesn't allow a paid service for your research, these are some places to start out.
