You are going to need galvanized pipe w/ drive couplings.Ive used schedule 40 in the past with no problems. Some well suppliers will have a drive weight that you can rent to hammer the pont into the ground. You will need a 2' piece of galvanized pipe for the weight to slide on and that will get atatched to each 5' section of galvanized pipe that you hammer into the ground.You should get a 4' 10 slot johnson well screen v wire type,the one that rancher showed you does not have the same amount of entrance area and will plug up much quicker. I would start the hole by getting a post hole digger and digging down 5' because you first section with the drive pipe,a section of pipe, and your point will be 11'. With the hole dug you will have a total of 6' sticking up wich will be much easier to deal with. The first section is always the hardest. Make sure each joint is super tight and always snug up the pipe every so often because the couplings below have a tendency to loosen up as you drive each section. You will also need someone to keep that pipe nice and straight as you drive the well.
