If you don't want to work with wood, T-posts are your next bet, as stated by previous poster. You could cover over top with 14' wide bird netting, which would put less drag on the perimeter fencing. This will keep them fairly safe during the day. Plan to lock them up in your predator proof coop each and every single night.
Or you could buy electric poultry netting. Check Premier 1. It's pricey, but the good thing is that it will deter even a bear. The only thing it won't keep out would be a weasel. I would still cover over the top with bird netting to keep hawks out. The good thing about the electronet fencing is that you can move it and re-configure your run area so you can move them to fresh grass.
If you could have your Dad come and help you set your posts, and do your horizontals, you could then attach the fencing yourself.
Take a trip to Home Depot or Lowes, and look at the chop saws. Talk to an employee about how easy they are to use. For the novice, who is fearful of handling shop tools, I recommend a chop saw over a skill saw. I was and still consider myself to be a novice, yet, after all the projects I've mentioned, plus a few furniture type projects, and playing with a chain saw, I still have all my fingers and toes.
