What makes you think that getting a new number will reduce your calls?  You may end up with a number that gets even more calls.  All numbers are recycled, and the person that had your soon to be new number got rid of it for the same reason you want to.  Invest in a call blocker.

Get rich quick scheme.  You don't have to WORK, you don't have to call people, you don't have to build a MLM tree --- give me a break!!!!
