Simple Project Change Voicemail of multiple phones numbers 2

This is for a very simple project. ***This is not cold calling or telemarketing*** I have hundreds of telephone numbers that needs each voicemail changed. All of the numbers are in the U.S.A So this project would be good for someone that has a way to make free unlimited phone calls. Like with Magic Jack or Skype It takes about 40 seconds for each phone number. The process is the following: 1. Call the phone number I provide. 2. Enter code to enter the voicemail manager 3. change voicemail to different name. 4. hang up and go on to the next number that I provide you in a list Thats it. It only takes 40 seconds each number. *****Please note how much you would charge for each number*****
