Hi Zuzana,
Please check out this page:
http://2much.net/websitetemplate.php
What we do is provide a fully functional webcam video chat system that you can customize as a part of your service to your customers. We have 2 basic templates including a fully "blank" template that you and your webmasters will have an easy time to design for.
LiveCamNetwork installs on his domain or sub domain, and uses your customer's own billing account with CCBill, Segpay, etc.
We can either charge your customer directly and pay you a commission, or we can sell licenses to you at a discount for you to mark-up. It's completely up to you.
Give us a call at 775-297-4979, or Toll Free at 1-866-892-5122 and ask for myself or for Kedra Alliard.
Cheers!
