Not counting labor you should be able to come in underbudget. I don't know how difficult it is to register a trailer there though. The main expense might wind up being the tires and the mounting method and any suspension you include.
The lightest tires available that will support your load will do. For budgetary reasons it would make sense to use wheels that mount a common tire size. Personally I'd probably go to a junk yard and ask for two matching, small tires. While you're at it see if they'll throw in the mounting hardware at a reasonable price.

I've molded some custom things for my motorcycle and used fiberglass (PC resin) to patch fairing cracks and dents. I'm told that marine grade fiberglass will last longer when exposed to the weather, but it's also more expensive. Given the option I would use the cheap stuff if you plan to seal both sides with paint.
For custom shapes I 1) Create a base shape with cardboard, clay, expanding spray foam, and/or regular foam. 2) I then cover the base shape with painters tape and/or Glad Press'n'seal. It's the only thin plastic I've found that mostly blocks the resin out. Some will sweat through though so make sure the plastic wrap isn't protecting something valuable. 3) I put fiberglass over that shape. The more curvy the shape is the thinner the strips of fiberglass I use. I also use a criss cross pattern, so that one layer has fiberglass strips laid vertically and the ones above/below are laid out horizontally. Sometimes I put pigment in to color the resin; it depends upon the application.
