how to locate companies which remediate for section 508?

Hi All,

Please reply off list as this may be a bit off topic.  I'm looking  
for listings of companies which remediate to section 508 web  
standards.  Is there a directory or listing and if so, a pointer  
would be appreciated.  If not, you can send company info to me:

Thanks!
