LibreOffice used to have templates for Avery's business card stationery.

I could not find any and I am assuming you tried it as well :(

Alternatively, you can go to Avery's website (a bit.ly URI), select the form type, create your biz card there, and download the PDF to print it on your printer.

I have done this for return address labels and it is awesome.

Caveat:  When printing - in the printer dialog box select "no margins" or the equivalent, print a test page on a blank sheet, and visually check for alignment with your stationery.  You have been warned :)

I also suggest that you include a QR code for your biz (the textual information) and put it in a corner of the card.  That way people who don't want to carry paper cards can scan your biz details.

Hope this helps.
