Add some features to my Shopify Store

I need someone who has experience with web developing and even better with Shopify to add a few features to my store. It is a Member's Only Store and it is a subscription based store which customers must pay a subscription of 9.99 per month to gain access to the store. Here are some things that I would like added to the store. For example when the customer buys a membership I want them to be able to see pages that non-members cannot see and also I need non-members to be able to see pages that members cannot see. That is the main feature I am trying to add and I know how much work is needed and it is not very difficult.
