Membership plug in

What I want to do is use the membership plug in to create custom order pages.

A customer contacts me wanting a custom set of grips, I want to be able to set up a page they will log into for their grips to submit payment for them.

I want it secure so that a different customer won't accidentally try and purchase the grips.

Is this a possible use for Membership, or is there a better way I should approach it?
