Mstboneyard, yours is an ambitious goal, for sure. On a good month, I can make that in fees, but every month may not be a 'good' month. Regardless of how hard I beat the bushes, it's not an amount that can be depended upon. I am not able to complete as many shops as others. My life and schedule have only a certain amount of time, also variable. You don't indicate if your "4 no-income producing days" are by choice or necessity. Certainly, shoppers who can shop upwards of 7 days a week would earn more.
So, you've become silver certified and haven't shopped yet? I'm assuming you believed the silver certification would help pave the way. Please read the forum, sign up with MSPs, apply and complete shops
BEFORE spending more money. Many, many shoppers have successfully worked for years without spending money for certifications, or companies promising pie in the sky shops if you pay a fee. All the information and assistance you need to mystery shop is here, free.
