I'm on the same page as Liz in thinking your health may be a major factor here. I'm shopping with serious health issues and I can't do as much as I could if I enjoyed strong health on a daily basis. If you have good weeks/bad weeks, this will work for you. Sometimes I shop up a storm for a few weeks and then I'll back off and not do much for a while. For me, this is perfect but I use it only for supplemental income.
You have to consider, too, how much work you can get. It depends on your location, how much competition there is in the area, and how many companies you sign up with. I'm located inside the Dallas Fort Worth Metroplex, so there's plenty of work if I drive. The only thing that holds me back is health and energy.
It would be very difficult, perhaps impossible with my issues, for me to bring in $1500 each and every month. It would be absolutely no problem to earn $1500 - $2000 monthly if I felt better. I've done it from time to time, but I don't work that much every month. I've been earning between $11,000 and $12,000 the last couple of years. I hope this information will be useful to you and I wish you the very best.
