Restriction on user

Hi,

I want to add some feature in my website can you please tell me something about that. I have some books also I have made post for each. now I want this is there any plugin so please share with me –

-If users are not logged in they can only read 300 words approx.

-If users are logged in they can read full content of books.

-But if users have not activated pack so they have to must watch 30-40 second’s video/advertisement if they want to read next book.

-If unpaid users have read four to five books with 30-40 second’s video/advertisement, so they have to see half hour video/advertisement before read next book.

-If users have paid so they can read book without any interruptions.

Thanks in advance
