Need advice on Membership plugins that have course creation

I am brand new to membership plugins, so apologies in advance if some of these "requirements" are obvious or available with every plug in. i am building a coaching website and have the following requirements:

1. allows for tiers of membership

2. allows for course creation and sharing

3. payments throough paypal stripe etc

4. private forums for members

5. easy to use once installed. I am adept at wordpress but do not want to be fussing endlessly.

6 not crazy expensive–like 500 a year or so?

can anyone advise me?
