What is a professional way to announce new business address and phone, like form post cards?

I want to find either something I can do myself (mass print on inkjet at office) or a service that can ECONOMICALLY do this for me. I could use a form letter but I do not know where to find one. And I need to do this quickly! I have been using various temporary contact numbers and PMB for several months now and this is hurting my clients and my future business.

The above answers are great. You can also go to OfficeMax or Staples, tell the people at the copy center what you need, and someone can design and print it up for you all at one place. It's not that expensive. I had to do it for my job a long time ago. I can't remember the pricing since I don't deal with paying the bills and stuff like that, but I know that it was a very easy process. Good luck!
