Mystery shopping is not something that will bring in a full time income. It can be fun and get you a few free items, like lunch or free movies, but the truth is that they pay very little for the amount of time involved. If you get $12 for a "shop", you have will probably spend two hours or more between the shop and filling out the reports. But, there are some times you can enjoy the assignment.
There are good companies and not so good companies. I am in NY, but my friend is in Virginia and she started working for the company who audited Wendy's. She regularly did those shops and most of the time, loved the food she was instructed to buy and had the reports down so she could do them fast.
But, don't expect it to be a gold mine.
I know this is a family site, but if you have the personality and the willingness, you can make decent money (and in some case BIG money) being an "adult telephone actress"....only women do well though. You would start out working for a "dispatch" company to learn the ropes and some people can easily make $12-16/hour. If you get good and can work for yourself, the money varies even more. Some people can make hundred a day/night. But, the economy has had a large effect on those earnings lately. It is a legit job, but lots of people's sensibilities won't allow them to consider it.
Customer service from home, like Alpine, is also a way to make money from home, but, yes, they are very strict. 1-800-FLOWERS was one of the companies who has at home customer care reps. I had one woman tell me a list of companies she had worked with via at home Customer Service, but I can't remember them all. They were assigned via a company like Alpine.
The more independent and entrepreneurial you are the more money you can make. I think there are quite a few people who do pretty well with Etsy, if they make their own creative items.
If you are great at something, consider offering seminars. You have to be able to market yourself, but I know a couple of people who do well with their smal businesses doing this.
Good luck to all of you looking!!!
