show different products to different customers

[bonecone]

I'm working on a website for a printing company. They print T-shirts, business cards, mugs, etc for other companies. A flash program has been developed and integrated with the Virtuemart checkout so that customers can upload images and position them where they want on a given product, resize them, add text, etc.

But I need to add more customization for individual customers. I want to set it up so that when a client logs in they only see, for example, t-shirts with their companys logo on it, and they can just add in the employee name they want on the shirt.

Are there any extensions that allow this level of customization in Virtuemart?
