I did a bunch of work for Pro Title last year. They paid and promptly. I was happy to do work for them and would again.

  The only issue I had with Pro Title is their communication leaves a lot to be desired.  I get the impression anyone, at any of their locations, can access any email.  This creates problems if the person that, for example, asked me a question regarding an abstract wasn't the person who opened my reply.  And as many of the emails to me were unsigned, I never knew who I was communicating with.
