Trading Card - Know any printers?

Im looking for a UK based printers that can print trading cards / cards similar size to the " Pokemon Card " Series ( which by the way I have no idea about standard sizes for pokemon cards or trading cards ( Im wanting to develop my own series of trading cards based around my own casual characters )
I would have thought any printers could handle these! Have you a local one you can get in touch with? I'm sure your online ones will do custom sizes, you just have to ask. And decide what material you want them printing on. Something like that I'd get laminated as it will be handled a lot.
