I just went through this, a month ago, I first made a separate email address, then I googled NCR printing and ncr forms, and just worked my way down, sending each one a form letter I created, I think I sent out aprx 30 quote requests LOL. don't jump right away when you start getting responses, give em about 2 weeks for all the responses to come in LOL.
I ended up going with a company (
http://www.printlinkonline.com) in Battle Creek, MI, they were a little over the lowest price but they were in the same state, and were very helpful. And they had their own system on their site for uploads, so I didn't have to email the files to them. plus their printer resolution was REALLY high so I could go really small print at high res on the TOS for the back and up load the large file with no problem. I think I payed aprx $145 for 1k of forms (2k of pages) booked in 100 (might be 50)
I included the form letter I used in case you want to mod it for your use.

I suggest spending a little time on some of the site to get a feel for what you might need and what they offer. Good luck!

Also, a good suggestion is to build your list first, and add em to the BCC list, that way after you decide who to go with your can use that list to inform the printers that a choice has been made and thank them for their submission.
