Xan....try this, it's a pretty good program and can do just about anything you will need. You can then go to any office supply and pick up the proper paper to print them on and voila!! You are in business!!!
I did not have the program either. I went to www.downloads.com (a share site for all kinds of free programs) and down loaded a program called "officeprinter 2.0" you can make letter heads, biz cards, envelopes, shipping labels, etc with this program. I bought biz card stock from Walmart for $3... used a basic color printer and get 10 cards per page that are already perforated. I just separate the cards and stack them nicely on my desk. I am sending a stack to my sister in Austin along with a flyer that looks exactly the same so she can post on her campus and in public meeting areas on cork boards. I also sent her a 3 month sub for 3 DVDs out for her effort... anyway the program "office printer 2.0" makes everything a simple 10 minute process. The logos can be resized by clicking on them and dragging them to the desired size on "word" documents and on "officeprinter 2.0". Anyway, it is awesome no matter how you do it!
