MDavisNowell,
I still consider myself new with video shopping so can't comment there. As to the $20,000 a year, here's what I did. I live on the cusp of a major metropolitan area. Besides mystery shopping, I started taking merchandising assignments. I often take the "orphans" that are not part of a regular rep's route. I am signed up with numerous companies. I always put my phone number on emails with schedulers. I often get assignments by phone.
The result has been that I have a fine mix of regular mystery shopping and merchandising assignments in my own town. I have regular small routes to neighboring towns. Some of the mystery shopping companies automatically schedule me.
The drawbacks: Because of your age, make sure that you pay attention to how much physical activity there is with a merchandising assignment before you accept it. I had a part-time job in merchandising that was nice but the same muscles were sore all the time. The applications usually ask how much you can lift, if you can stand on your feet, and whether you can bend repeatedly. There are lots of those assignments that are easy.
The advantage of merchandising over mystery shopping is that you hardly ever lose money. Practically no one calls to ask why you did it that way. It has its own kinds of stress, but they aren't huge.
The other drawback is that in order to accomplish this and make $20,000, I worked constantly. I accepted everything. Now I know how much work I can physically and mentally do. You may not want to get to that stage, but seeing how far you do want to get is a fun part.
I have so many contacts now that I'm not afraid of dropping the nuisance assignments, but I am planning to build up the video work. As Carrie said, it is stressful, at least right now, but I like the work. I will probably still take other work for a while after I get a regular schedule with videos, until the time comes when things are running smoothly enough that I have to drop them.
