I don't understanding your pricing. Well, most web based app subscriptions are based on time. Instead of forcing people to pay for time they won't use or need (e.g., a monthly subscription or longer), you can get as little as a day, and add more as you need it. If I choose the basic plan, can I create unlimited e-books for one day Yes.
