Maybe you could make a trial that only allows you to make X amount of articles in total? Then if they wanted to use it further they'd have to buy it.
I'm an idiot when it comes to setting things up, but if you could make a trial just so I could get a feel for it (I am a quick learner) I be pretty interested.
Brent, Thanks for the encouragement, for fear of repeating myself I'll just remind folks that I need help selling the program and am offering 50% commission on sales if anyone would like to try their hand at a PPC campaign. I'll also consider raising the price of the product. Feedback has been overwhelmingly positive and there's a serious feature list for the next version, but I'm a PPC newb, now learning fast, so help would be very welcome. This is a good product and in the right hands can sell well. Thanks, Jeremy
That did it... Much improved... I'll have a better play with it now... Look forward to giving you some feedback.
