Super Freak Pumpkin and Gremlin Gourd.

I'm starting my first pumpkin patch next spring and I was wondering if anyone grew these or has seeds from them. I posted in the seed exchange forum but since I don't have any seeds to trade, i'm not sure how that will turn out. I saw these listed in the Sieger's magizine but I didn't want to pay $40 for 500 seeds when my patch is only...100 sq feet.

Second part of the post is what I did to get the soil ready, I dug it all up and put down a layer of corn stalks then spread about 200 lbs of potatoes on them for the N, about 3-4 inches of soil on top of that, then I put down 6 inches of leaves ( now 3-4 inches after the rain).
