Help Required, Shopping cart with diff products 4 diff users

[Magikos]

Hi and thanks for taking time to read my post,

I have photographer friend of mine that is looking to have a site which will allow her to have a different set of images (effectively a private gallery) and allow clients to choose which photographs they would like in whatever size they would like it, choose frames or not and then checkout in one of two ways - either by just Emailing her a list of what someone has chosen and processing the costs / charges manually and then later to have this enabled so it will process the charges online and checkout via a credit card purchase. 

Challenge I am unsure about - each of her clients will login to the site and then we would like to be able to display only their photographs (essentially their private products list).    Is this possible and if so how could I achieve this

Will need to know if I can have different products available for different logged in users and what configuration I would need 

Any advice and guidance would be most welcome.

Thanks in advance for your time.

Regards,

Magikos.
