Its fairly easy to do. You need a pragram like PintMaster, Printshop, etc. They have a template for business cards. Just make a number of cards and print them out. You can even buy pre perforated biz card paper. However i would suggest a cardstock as it will stand up better.
Instead of laminating the cards i would suggest you just buy some heavy duty clear packing tape. Laminating the cards will run into money fast and it is really not that important.
Just print out your cards and tape them up, then trim, easy
