SSDI/SSI leads

I am an attorney practicing for a firm that handles personal injury, workers compensation, and Social Security Disability cases. We travel throughout the country for the SSDI/SSI cases. The firm I work for provides a very favorable fee-sharing system for all the cases we bring in (50-50 split), so I’m looking to expand my personal intakes while he still offers this. Because I know the leads will be slightly cheaper, I am looking to generate a very small amount of SSDI leads in the southern states to start. I am also looking for help refining my website.
