If you have time, I highly recommend reading The 1% Windfall by Rafi Mohammed[1].
There are dozens of pricing options in the book; however, Rafi's favored model is: try to set a price based on the value the buyer receives.
In your case, it sounds like you are the buyer because you built something that fixes a problem you had. If the pricing is something you will pay, then you're probably in the ballpark with your prices.
Have you surveyed other theme/module sellers to determine the value a service like yours would provide to them? Using your scenario, will other sellers value (pay) for your service at the equivalent of 2 sales/month for the Pro plan and 4-6 for the Platinum? Will you pay that much to a competitor if they build a similar business?
Good luck with your product! If I were a theme or module seller, it looks like something I might try because as a regular theme and module buyer, nothing frustrates me more than to click a demo link only to find demos that do not exist anymore. I almost never buy a theme or module that I can't demo first.
