How much would you be willing to pay?

So something like Mixergy in the IM niche?

I would say go for $25. You can then negotiate with product owner to provide you exclusive discount and a cut as well.

Personally I would go with 47 a month based off month to month recurring payments, Maybe do 27 or 37 for those individuals who would like to buy a 6 month subscription, and arrange the 97 dollar plan to include something that gives it a premium value?
