Product visibility

Hi,

I’m looking for a solution.

I need to make products visible only to a specific user.

So let’s say Mary J come to my site and creates and account. I want Mary to only be able to see and purchase 5 different, specific products.

But when Suzie Q comes to ym site and creates an account, she cannot see or purchase items designated to Mary J. Only items that we designate to her.

So I need to assign products and their visibility only to a specific user. Not the rest of the users/visitors to my site.
