Blackberry 10 Mobile Dialer

I am looking for someone to develop a app basically a dialer, when people use the dialer to make a call it calls a unique number first, pauses a few seconds then enters a password then dials the number through the regular cellular service. What basically happens when a user calls that number our system checks if it recognizes the caller ID if it does recognize the caller ID it prompts for a password, if the password succeeds it gives a dialtone to dial any number, instead of users needing to follow below steps we would like to make it simple they dial the regular number and the action happens by itself. Currently I would like to use it with the Blackberry 10.
