I was thinking Specific Post/Page Access, but it seems to remove the "Member" feel. Since they are only receiving link, and not login access to a membership area.
I can see where it may appear this way from the surface. But in practice, it's not so bad. If a Member is logged in already, they are really just purchasing additional access to something else that you're selling separately. So in your case, you could have everyone signup for an account, and then use Specific Post/Page Access once they're logged in. This way you're not losing the Membership feel.
The end result is that Specific Post/Page Access works with OR without Membership Level Access being required. It's fine if they are already a Member; they can still spend more money with you, in order to pay for something that is sold separately.
In regard to setting up the custom capabilities, is this something I could hire you to do? or do you have any recommendations?
Normally, yes; but given my current workload, I'll have to respectfully decline at this time. I recommend
Elance.com. You can post a Project description there and take in bids. It's free to do that! Once you're comfortable with someone, you can accept their proposal and work will begin to your satisfaction. There are many developers at Elance.com that are familar with s2Member.
Alternatively, or in addition to Elance... you can post a project request here:
viewforum.php?f=33Up until now, this forum has been a little slow with respect to custom programming requests, mostly due to the fact that I've been taking the burden upon myself to handle custom programming for our clients.
Going forward into the future, we'll be farming this out more. This way we ( the development team for s2Member ) can remain focused on the core concepts of the application.
