Sites to use: LiveJasmin

"LiveJasmin is the first site where I started modeling, so because of this, I have acquired a solid list of regular customers. I have found that while traffic is not the highest on LiveJasmin, the customer loyalty is overwhelming and the amount of time customers spend with you makes it extremely worth while to spend some time there getting to know people. On LiveJasmin, I can easily make $100 - $200 in an hour from the regulars.
........ When you first log on after creating your account DON'T GET DISCOURAGED if you don't make any money right away. When you read articles on how to become a web cam model, you hear about the jaw dropping figures people make and it is extremely enticing. Yes, people do make that much money (people who have been on for years with a solid fan base and understand how to maximize sales by lighting, camera positions, flirting, etc.). No, it doesn't happen the minute you log on. It took me about 2 weeks to really make any decent money. You have to be patient. Remember, it is expensive to pay to watch someone on cam. You have to prove to the viewers that you are worth it. They need to like you. They need to feel that you connect with them. They do not want to pay for some unattainable picture perfect person they know they will never get. They want to spend time with someone who is real. Someone who, maybe, just maybe, they can meet. (Which will - and should NEVER happen). If you can prove to them that you like spending time with them, and that their time with you is valuable, then you will see the money start to come in, and by the 3rd or 4th week, it will be coming in by the hundreds.
 .........One tip I wish I would have known. Maybe it's why it took me so long to make money right away. GET YOUR PICTURE UP IMMEDIATELY. I went for about 3 weeks with no profile picture. All I had was a silhouette that said "New Performer." I'm sure that did not help me at all. And in my profile, I did not use a face pic. I used a body shot. I personally just felt more comfortable doing that. When you are a new performer, you will also be "on sale" to customers. Take advantage of this. If you are a new performer with your picture up, customers will be looking at you right away. And if you are "on sale" and they like your picture, they feel it is worthwhile to stop in your room and hangout. When they do, TALK TO THEM. Hook them with your wit and charm. make them take advantage of the promotional new performer price and make them become YOUR regular customers. This new performer promotional period is the best way to get paying customers to visit you and become regulars. I was so mad when I learned how everything worked, and that I completely missed that opportunity. I always think about how much more I could be making if I would have used the new performer promotional period to my advantage."
