Based off the photos I would try building something like this below
I'll separate the 3 components so you can build/source them separately
End Rail: try sourcing a "safety rail" or "guard rail" from an industrial supplier that is 18" high. They may have a premade piece that will work for the bar hop end. Otherwise this is a custom weld job and you'll just have to take the finished box to them and just tell them what you want made. It will be a lot easier to get a rail to bar hop vs a rail you can grind
Box Piece: 3ft length x 2ft width x 18" height. You can youtube how to build a box out of 2x2 or 2x4, its pretty easy. Reinforce it so its heavy and doesn't move or bend under weight. Use 1/2" plywood for the top and if you can get it Skatelite or Gator skin. If you cant get that then use "good one side" plywood with a finished surface so it's smooth. Use outdoor primer to seal it if you live in a rainy environment
Ramp: 3ft long, 18" high right angle triangle. Reinforce with 2x2s. make sure to fasten to the main box very well
Good luck. Have fun. Show us what you end up making!
