I wish I had before pictures but basically my garage floor was completely covered. I would use 2 feet inside the garage and park the car outside and that would be my "organized" area. It took me 15 minutes to find a tool I just used yesterday.
Here is hints and tips on how to organize your shop. The actual process and some of the organizational accessories.
Step 1: Sorting
The way I love to do it is to start throwing things around. I usually go to Goodwill or the likes and get plastic tubs for about $2 a piece. you can also use boxes, but this can be frustrating when the bottom breaks and can't be used as easily again later. Your local grocery store has boxes they give for free if they have some.
Decide what each box, bin, or Ziploc bag is going to be for.(or decide as you go.) start throwing all the misc. tools in a box. All the scrap metal in another, Cords and electronics in another, Welding supply, specialty tools, nuts & bolts & screws & nails, Epoxies, whatever you work with just organize it in some manner.
