Just browsing the forum to get a feel for the place..my suggestion on this would be to get 3 sets of business cards, the outer two on 400gsm matt lam / gloss lam, whatever you are looking for! Also buy ( from the same printer to ensure sizings ) another set of blank cards in the colour you want. It is then a painstaking case of sticking them all together yourself. If you put the time and effort in they will look great...but whether it is worth spending about 10mins per card is up to you!
Cost or effort ..... reduce one, increase the other!
