Unique category/content for one group or one user

Hi! This might be an odd thought, but here's what I'm looking for;
I want to allow user A to be able to log in and see Category A. User B, category B - and so on.

Example: I (site admin) register an existing customer from my flower shop, let's call him John Doe, and then I create a specific category for him called "John's Stuff" and fill it with stuff that only John should be able to order from my webshop. I send the username and password to John and tell him that his unique little webshop is open for business. Then I create another HikaShop user, Jane Doe, for another existing customer from my brick & mortar shop and create the category "Jane's stuff" for her. Now - when John logs on - he can browse through "his items" in my webshop without being able to see Jane's stuff, and the other way around.

The question is, is it possible to associate a unique category with a specific user? If this can't be done by normal tweaking of the code somehow, how much would it cost me if I ask one of you guys to modify the code for me? I'm not a programmer, by far, but I do know what I need to keep my customers happy

Don't get me wrong, HikaShop is fantastic, but the idea above would allow me to reach out to a new group of clients with unique needs.

That's awsome. I will absolutely keep my eyes open for that update. If it comes out in time, and works, I feel certain that a Business Licence is worth the price. Speaking of that, I will now return yo your main site and see how much you ask for the business edition.

Keep up the good work!!
