If you have more than one cubic yard to pour, I would strongly suggest a
ready-mix concrete service instead of trying to mix your own.
If you have less than a cubic yard, you might consider doing it yourself with
bagged concrete. It really isn't that hard to work with, you just have to be
able to lift the 60-90 lb bags. Don't hurt yourself.
If you are mixing more than 3-4 bags, I would STRONGLY recommend renting a
small mixer at your local home construction store. Much less work than trying
to mix a bag at a time in a wheelbarrow.
My Rohn 25 tower base took 28 bags of concrete. I wrote about it here on my
blog:

The picture quality isn't great, but you do see a picture of the small electric
mixer I used, plus my technique for doing the pour. Pouring the base took about
2 hours of constant work.
