You're looking for something like this? MTG Cammander's Arsenal 100hp Spindown
These are very expensive, not sure how you'd get them cheaper. I've done a little Googling and come up with nothing. Perhaps you could get them 3D printed by Shapeways
In any case, I'd be concerned about how expensive these are, if you want to implement them across a game you want to sell it will become very prohibitive, and even if you managed to fund the release the game would have to be so expensive it would be hard to sell.
I'd recomened considering other systems, such as counters or even pen and paper. With counters you could provide counters that have various numerical values (in Magic I use little gems I got from China as +1/+1 counters, white = 1, green = 5 and red = 10) and with pen and paper you could provide wipe clean cards.
I'm concerned that even if you can make these work the board will be very chunky, making for bigger boxes and further logistical issues. Here's another idea I just had: 3 disks of varying sizes, made of cardboard, with numbers printed on them, that can be pinned flat to the tile:
This would take up less space and allow other things to be placed on the tile, as well as being vastly cheaper. The player would just turn the wheels to align with the arrow (perhaps better to have the arrow on the left hand side)
