Custom paper and product types when self fulfilling

I'm self fulfilling prints on my site partly because I can offer a number of print types that aren't on offer through Fotomoto. For example, one lab here in the UK offers bromide B&W printing, which Fotomoto doesn't. I can also offer a wider variety of paper types.

This is fine but I'm struggling to find a way to describe these products. Is there a way to do this?
