Sell capability to submit a limited number of entries

I would like to sell to users the capability to submit entries in my Gravity Form. Their purchase would essentially increate their limit of the number of entries they can submit. As they submit entires, their remaining entries would decrease. I image that WooCommerce might have a product that provides this ability?

If this is possible, it would be nice, then, to show a user how many entries they have remaining. This functionality would work really nice in conjunction with the Advanced Post Creation Add-On.

How might you accomplish this? Thanks for any tips!
