Cheapest solution:
Old mobile home frame or camper trailer frame - $250 to $300
Two new 5,200 # axles, with brakes - $800 (if the old ones are outer-lug mobile home wheels you don't want to use them)
Used 16" 6-lug Chevy truck rims and LT tires from Craigslist/junkyard - $200
Wiring/lights - $50
For about $800-$1500, you can have a 10K trailer built the way you want it. You didn't mention whether you have a heavy truck or not, and a brake controller. For towing anything over 1/2 a cord, you want at least 3500# axles and that means a brake controller ($85 for a Prodigy, the best deal out there). If you have any specific trailer or towing questions, PM me it's a hobby. At the least, make sure whatever you get has 3500# axles, and a 2 and 5/16 ball. Anything near 10K in weight you will want a weight-distributing hitch for if possible.
