Tree Planting

[Hoover]

I went a little crazy yesterday and bought a much of good sized trees for my house. We built it in 2010 but have yet to landscape, so I have a blank canvas.

Anyway, I bought 15 trees or so and need to get them in the ground.

Any advice in how the best way to do this is. I'm not going to use a shovel and do it by hand. What do i need to rent or how expensive is it to have it done?

Thanks.
