Look in the Thomas Register at the local or nearest library (Shreveport/Bossier) and look for product development firms. Pick the one with the best reputation and inquire their schedule, previous clients and willingness to sign a non-disclosure agreement regarding your friends' idea.

Seeking a patent too soon is like providing competition with a hunting license. Too many lurkers viewing the paperwork. Depending upon the application of the device or patentable process, get it to market ASAP while keeping the secret about it to yourselves as much as possible.

Good luck to him. It is a long and arduous task... almost as difficult as the songwriting process in today's convoluted market... LOL!

Best,
