I worked as a chat line operator before I came into escorting. In order to make the same money as a FT job depends on what the companies pay per minute and all the things that go with it. I found the times that were busiest was when the wives/partners went to bed but if you have to get up for work the next day this is difficult. Have you worked out how many hours a week you would have to work to make the same as you do in your FT job. You may be shocked. There is also the fact that every week is so so different and nothing is a definitive.
Feel free to PM me for any further info if you need to.
