How important are business cards? Well, they are one item that I decided to invest in near the birth of my wedding photography business, and it's been a great buy. I use a company called Moo.com, and I've never looked back. I can't rave about them enough, they are very professional, offer a wide range of personalised business cards, and have a quick dispatch time too. They also offer personalised stickers which are great for logos for packaging things like prints.
Having a little mini portfolio carried around with me has been fantastic for my business, and obviously it gives a good impression...
