So finally, some concrete news. After going through every option on how to make these both effectively and accurately, I decided it best to waterjet them. A lathe would work, to do it I was going to originally get a stock about 8 inches long, turn down the OD and then bore the ID, then chop em off with the lathe internally...but it wouldn't be perfect thickness between them, and take a long while to do, my access to the lathe is limited. Now I don't personally have access to my own waterjet, but where I work uses a company and we get good deals etc....so I went that way. They quoted me 13 each....and that is due to low quantities...if I made 100 it would be 5 each.... So there you have it, 13 each plus shipping, I know that is more than steahly charges for theirs....but after shipping, it should be as I quoted you...15-16 I think I will use USPS, its fastest and cheapest. Here is how I will go about getting them to you. Email me at mhsgolfstud at gmail.com how many you want, the shipping address, and paypal information to send you an invoice. Once I have received payment....they will be off to you! I plan on shipping them out all at the same time....so two fridays from now you will have it. Sorry it took longer than expected, and cost more than even I expected. Just know that if I don't sell all the ones I ordered...it costs me money out of pocket, so I am not ripping you off! Oh yea, they are 3mm thick.
