Page restrict plugin and WooCommerce

I have a website, and on that site i have one page that i’m using for some documents and only users i have registered can access them. Now i need to create page with WooCommerce, but if i allow others to register, they will be able to see my documents also, so is there any plugin that i can restrict that page to some users with certain usernames, or role, or something like that. Thanks in advance.
