So I finally received a quote from Rio Grande after two months of pestering them. Hurrah!

However, elation was short lived once I saw the amount - $25. Boo.

The unit cost (that's up to 5000 units) is way too high to make the game financially viable. I've gone back for more clarification as to why that is. Next to what's in a box of Rattlebones, most of what I'm asking is comparable or less (number of dice, number of faces and face colors) except for the face designs, where IMDL! has more. 

If that's the issue, I can work on it but the price has got to come down otherwise it'll be back to the drawing board to a certain extent.

Disappointed but i haven't given up hope yet. There's more than one way to 'roll a die'.
