user8167: I am looking for a large ePaper Display for the Arduino. The issue is is that I cannot seem to find one any larger than 4.5 inches in size. That will be compatible with arduino. Even with a controller board. 
Are there any companies that sell controller boards for these displays? Is there anyone who can manufacture these epd displays upon request?
I am looking to take this project to a pcb board after I prototype it so do I need to build my own controller? If what parts would you need? Is it easy for a designer with intermediate capability? 
I can find all kinds of display like at pervasivedisplays.com and Mouser.com
The end goal is to create a Arduino based project that I can score skeet with to keep track of my average score. 

user7856: I would suggest you to start the other way: find a sw stack that is known to work and check if any of the controllers/displays it already supports fits your needs. This is how I would do it.
Here is a starting point.
