I don't know anything about Paul, or his site - but every time I see a new opportunity, the first thing I do is a Google search of a review:
Google: "partnerwithpaul review"
Now, a lot of them will be people getting leads by plugging the system (or bashing it, in order to promote their own) - but many times (you may have to go through a bunch of pages) you can find a review that goes into every detail of the system giving you enough to determine if it is something you can or want to do.
I personally wouldn't work anything (or with anyone) unless I could establish communications with a sponsor to get real information in terms of what I am doing, what to "realistically" expect, determine what my upline is like, etc..
I wouldn't spend a dime otherwise.
It sounds like a "funded proposal"
Good luck!
