I've done my own alignment and it's not very difficult.

Here's one website:

What I did was use two boards and two measuring tapes.

Put one board on each side of the car and measure from the front of the wheel AND one tape on the back of the wheel to see if your car is toe-in or toe-out.

Then adjust the turnbuckle for the toe adjustment. Do the same for the rear.
