Replying to Terrain park

sad but true the local hill that i ski at does not have a terrain park. we are stuck with building our own jumps and upkeeping them. finally this year there has been some talk that next year we will be able to maybe get one. the problem is that no one has a clue on what to build or what to set up. so they have asked me and my friends. i have know problem building the rails becuase me and my friends have axsis to a welder and a pipe bender. but the jumps on the other hand need someone that knows what there doing like with the snow guns and the groomer. so my question is, is there any plans or blue prints on how to make tables,step downs or any other jumps that these idoits that run the hill could understand.
