Utility trailer question- how to make it work?

This one is the full 4' wide cargo space I've measured, and 6' length plus the ramp.
Frankly I just think size-wise the 4 X 6 is perfect for my needs except I'd like to be able to move 4 X 8 panels on those rare occasions.
If the ramp were only 2 ft long that would be ideal I think. I'd just rig it to lay out like a truck gate and I'd be set.
I called around and found a welding shop that says they will do it for $100. No idea what the typical cost is. Guess I'll kick it over.
