because there are too many turnkey scripts and sites already running on the net which are to be honest, SHITE! most of them make the owners zero money, without investing a lot of hours into marketing etc etc. honestly mate, i wouldnt consider any turnkey solution. the market is too saturated with this kind of stuff, and is poluting the internet with duplicate content which is worthless.
What about this script I made? www.allurmedia.com not strictly a turnkey script, but still, I'm selling copies.
