I need to find a place where they make those cardboard people. I need one of Joe Jonas (from the jonas brothers) by December 16, hopefully! The first person to give me a valid place that will make me one i will choose as best answer! thanks soo much!

There are several places on-line that offer services like this such as Party Standups and the Advanced Graphics. They are around $100-$200 dollars for custom ones last time I checked, and you will have to supply your own image.

If you're looking for something locally I would suggest looking for a custom print shop in your local Yellow Pages. Not all of them will be able to handle something like this but if you ask around you should be able to find one.
