It's pretty much always cheaper to buy premade panels as opposed to building yourself.

Dig post holes 24" deep and use pressure treated posts. A lot of premade panels they sell use a pressure treated 2x6 on the bottom so the area most in contact with the ground will not rot away.

Get the green treatement for your post cuts and stain your panels with a clear eurethane in the summer once they've been completely dry for a few days and you'll be good for 12-15 years
