Seriously, check the pics in the link earlier and here:
It isn't rocket science: (per side) measure and cut one piece of U channel. Measure and cut one piece of box (eg that's about 3 minutes...). Drill two mounting holes in rear face of U to bolt to transom, then matching central pivot holes in U and box. Then upper and lower locking pin holes in U and box.
One more hole at base of box for wheel spindle. The odd washer, spacer, bolt nut, squeeze of mastic here and there. Maybe an hour or so? Materials cost - beg, steal, borrow, buy but a fraction of your US dollars (400?!) for sure, maybe £30 to £40?
I guess though most of us are talking 75 kg all in small SIBS, your 500 lb. is trailer territory.
There are some nice commercial sets out there but making your own is very easy and economical.
