Unfortunately I don't know how much it costs to build one as I was given a bunch of square tubing in exchange for rebuilding a friends skid steer trailer. Between what I had on hand and what I was given I had everything to build it on hand. I also don't know how much time I invested as I just worked on it whenever I didn't have another project. A couple of hours here and a couple there and before long it was done. I'm not much help am I?
