I can demo many webcam sites we have completed in the past just contact me. I can't post links here as most of my clients prefer not to post that information in forums (everyone understand why)
We are building webcam sites for 8 years, can offer full scope of software and graphics design services! The same time our office works from Russia and we can offer competitive prices for building it up and further support.
We also have chatroulette script if anyone interested
