Where to get custom trailer (or mod) San Diego

[Bruntoj]

Where's a good place to get either a custom trailer or modifications to a stock trailer, preferably around San Diego county? I'm looking at buying 2 kayaks: A Pro Angler + Outback/Revo and really like the idea of a double decker trailer similar to this. I need something as narrow as possible (50") with a retractable tongue if possible to help with garage space.

I found this pic on another forum, and frankly don't know where to start.

Or this


Much appreciated
