3D diagrams for assembling a foot rest

I need to get a series of 3D images created (in CAD or Sketchup or something) that will show how to assemble a footrest. I have included pictures of the footrest being assembled and I am looking to have easy to follow 3d diagrams for each step in the process. The footrest is very straight forward. I need just three steps based on the three pictures provided. Think of assembly diagrams like you would see in IKEA furniture. The final output of the pictures need to be something I can put on the web or a word document. 1. Picture 1 is of how the foot stool arrives with all the loose parts 2. Picture 2 is of the body of the foot rest flipped over with the back feet now folded out (they are pre attached to the body), and the front feet attached with the bolts, nuts an washers. It would be nice to see in the picture the bolts nuts and washers in an exploded view as if they were going through the holes. 3. Picture of the completed unit turned right side up. I have 3 or 4 more of these with more complex assemblies (Chairs/Benches/Tables/Sheds) that I will be looking for in the future. But I want to start with this simple one and find someone I can work with. The dimensions of the footrest (although I do not need these to be exact for the diagrams) are 18 inches from back to front, 15 inches wide, the exposed portion of the back leg is about 8 inches, the exposed portion of the front leg is about 5 inches. The footrest portion (excluding the height of the legs) is about 6 inches in height at its highest point. I do want the diagram to show the individual slats on top of the foot rest.
