Hello Richard,
I'm working with an affiliate script which is extremely powerful. It's not quite ready for release to the general public yet. We've still got documentation to finish on it.
I'm a little puzzled as to why you don't want anyone to make a referral to you if they're an affiliate?
If it matters, I'm an affiliate, I use this script, I'm writing the documentation, and I'll be installing it for a fair price. Who know's, I may even set up a way that I can just rent the service.
That doesn't make the script any less powerful, or the price particularly higher. It just means I firmly believe in the product.
You can see it in action at my site.
