create membership site on WordPress

I have a website on Word Press called about watercolourpaintingbasics. I have many video tutorials teaching watercolour painting. These videos are uploaded to WordPress. I want my customers to sign up for their membership and then recieve a video every two weeks.. This needs to be integrated with Word Press, Paypal and Aweber. I have already created the optin page and sales page. But they are showing on the google page and so the people would not have to pay but can already get it - so this needs fixing so that the customers can only get this data once they have paid. I need you to set up this site so that my customers can join the course and get drip fed the tutorials once every two weeks. Obviously potential customers will start at different times but all need to do the course in the correct order of tutorials. They will pay automatically every 14 days.
