Customization to theme

We have purchased the Vantage and Directory child theme. We are looking for optimizations to the themes. 1. We need for there to be more choices in the price packages. The packages should be able to offer a)videos, b)various # of images, c)an area for short description, d)an area for long descriptions. All of these options would be able to be chosen from the wp-admin area to offer in different price packages. 2. Where it shows on the packages: "Feature on Homepage for 30 days [Add $0.00]. Feature on Category for 30 days [Add $0.00]" We want to have the option for that to be visible or not. Also, where it says: "Please choose a recurring payments option: Automatically charge my account to renew my listing Do not automatically charge my account - I will renew manually", we want the ability to have that show or not. 3. The ability for ads to not show up on those who pay for a premium subscritpion.
