I am going to guess that you are talking about a proof you could show to a client? Many clients would be able to view it online, if you send them a jpeg/pdf in their email they will be able to view it, just make sure to watermark it to prevent theft. If you need to show them a physical copy, I'm sure there are local print shops around that you may be able to get a membership to reduce prices. Here in Canada we have STAPLES, which will print anything and has quite a few choices for stock to print on, just look around your town!
