I am super excited about receiving theses dice and hope that the images will fit nicely on the d12 :-D The sales rep said they could use a larger dice if needed , but he thought the images would fit on a standard d12.
For anyone out there that is interested in making custom dice, here is some info that I found out. Most places want a very large minimum order; like 100 or so. This brings the price of making them way down, but I don't need 100 dice for like $400-500. I needed d12's and a very small order.
I came across Chessex first. When I emailed them I asked them what there minimum order was and they said 10 dice of any kind. But a custom dice costs $1 per side. So an order of ten d12's would cost $120 plus S&H!
I then came across www.customdice.com and their dice are $1 for the blank dice and $1 for each custom face you put on it (This means that even if you add the standard numbers you are still being charged $1 for it). But they are willing to do different color on each face and there is a minimum charge of $40. So i went with the 3 custom d12's for $39 + $6 for S&H (Total: $45).
I hope the dice look really good so I can recommend them to other friends who are making their own board games :-D
Here are the images (again) in the colors that I selected:
