I want to create a simple WP membership

I am interested in hiring a developer to set up a very simple WP membership website. I want to integrate the membership website into my PayPal express account and deliver drip content monthly to my members. There is only one level of membership and as the client signs up they get the drip content. Month 1 #1 PDF download, Month 2 #2 PDF download, etc..

Can this be done simply?
