Request to buy pumpkin seed thresher for Canada

We are a small producer of hulless pumpkins and our biggest bottleneck is crushing the pumpkins and removing the seeds - all done by hand right now.
We are looking for a small unit that we can feed pumpkins into and have the pumpkin crushed and the seeds threshed out.
if you have such a unit or would sell plans for us to build one please contact us with price and if possible estimated delivery cost.
