How can we charge for days of listings?

[ReignForever.com]

I would like to offer my users 3-7 day listings for free and charge (by Paypal) different rates for 10, 15, 30, 60, 90 day listings. I would also like to disable No Expiration date listings. How can I do this?

Thank you

You can remove no expiration from the uploadproduct templates from the duration select box option

As far as the rest that would require you to heavily modify your code as that is not how the current payment system works, it is charge per category.

You can post in the modifications forums for things such as this that fall outside product support.
