question about membership plugin


I have a client who has a premium access website he wants to charge 5 bucks a month for. There’s the lite site and then this one.

so its pretty simple. I was about to head off and find some company or plugin but I thought of wpmu and thought I’d ask if this sounds like the kind of thing I should be using the membership plugin for.

would this allow me to have a setup with sending people username and passwords and allowing them access to the premium site?

I want this to be super easy and he doesn’t mind paying a bit for something. If this isn’t the solution I would certainly take some advice from people who might know of an alternative.
