Thank you for the very constructive advice. I slept on it and I think I will go for the second option instead: as you say I'm in the price discovery phase, and if people don't want to pay, what I can do is offer more value for the price.

The credit system is an excellent idea that would need some infrastructure to support but I already had a couple beta customers mention they dislike subscription model and would rather pay once when they need the product.

Thanks again!
