Hi Erik,
I recommend to go with any other ready-made webcam scripts instead of modelcentro because you'll receive 66.5% commission where in your own site you'll get the full amount. You can try 'xCams by Adent' for this.
You should update your content in every 2days to generate more traffic and money. It would be great if you could update it in regular basis.
Your niche is good. There is demand of big facials. I suggest you to explore other niche also as the time flies. Initially you can start with your niche.
You can visit this page
https://adent.io/products/xcams/ and write to us. We would be glad to help you in this matter.
Good luck!!
