Hello Tigerin - Some of us make a living doing this, but most of us don't. That doesn't mean you can't, but it does mean that most of us who do this aren't trying to make it work as a sole source of income. What you could easily do is increase the amount of shopping you're doing while you still have a regular job. There are two good reasons for you to do this.
(1) This will allow you to build a solid savings account, which will provide the freedom to make less stressful decisions in the future. Independence is money in the bank. A good plan would be to save up a few months living expenses before jumping into auditing/mystery shopping full time.
(2) You will become familiar with an increased work load, which will be your unrelenting companion if you decide to do this full time.
You've done 100 jobs in six months, which is 16 jobs per month. Start thinking about eight or more jobs a day - finding them, booking them, learning the guidelines, shopping/auditing, and reporting. You can do this many on the days you're not at your regular job, and you need to do this many to get used to what is required.
When and if you go full time it will be harder than holding down a full time job and there will be no benefits at all. The pay check will not be a given and it will not arrive on a certain day. Sometimes you will work for nothing, either because of your own error or because of circumstances you can't control. On the other hand, you will have personal freedom and will control your own time.
I understand video pays much better than non-video shops, so if you get into video it would make a difference in your income. However, I also understand that the rotation on the video shops may be much longer and more traveling over greater distances may be required. There are several threads on the forum that discuss video shopping, and you can do a search on them. The video shoppers have been really good to share information on the forum.
If you average $15.00 per shop in fees and useful reimbursements, you will need to do 2,000 shops per year to reach $30,000.
If you work five days a week, that's 260 work days per year. That will average out to about eight shops a day, which is a load when you consider search time, prep time, work time, and reporting time. There are a lot of people who work harder for less, but you have to decide how hard you're willing to work at this and whether you can generate the money you need to meet your obligations now and in the near future.
I'm optimistic for your prospects if you're in an area where you can get enough work. I do recommend that you don't give up your job until you have a substantial savings account to support yourself for a while. If you don't have the discipline required to shop part time and save the money so you can try this full time, then you probably don't have the discipline to make this work.
