I really need some business card templates at the standard credit card size of
85mm x 55mm with 3mm bleed on each edge.

I saw this online, which I guess would be helpful

http://site.xara.com/products/xtreme/bizzsets.asp

However, when I follow the instructions and click 'get clipart' nothing happens.

Any suggestions? Xara seems to work only in pix, when I need to specify mm.
