Batboard

I used to see a company that would advertise that they would add stored voice to a low band Minitor IV. I can't find the information for them and have one that needs it added. Can anyone add it to me for a reasonable price or know of any companies that will do it? The pager is already out of warranty so I'm not concerned about voiding a warranty. Thanks.

Bump.......Surely someone has the capabilities to do this. Any help would really be appreciated. If you can't do it, but know someone who can, please let me know. Thanks.
