Php programmers are very desired nowadays. Have you tried direct cooperating with variosu companies? You might be paid regulary then.
I see. In the first post you said php scripts. Your site seems to have one script. The question I have did you have any sales at all? If you did, what venues did you use? On the other hand, almost every web hosting provider has their own statistics calculators. Kind of hard to beat those.
You mean awstats? Or any others that rely on the raw logs to generate statistics? I used to have more scripts, but they're kindda obsolete now, maybe you have an idea of a script with high demand?
