I made my own wheel for my outcst about 5 years ago. It also doubles as a pulley for my anchor. It really wasn't that tough if you weld. I used the front wheen from my sons first bike, fashoned some forks, and bought tubing slightly smaller than the tube on my frame. I cut the frame, insert the wheel assembly and I use to set pins to hold it at the right angle. Works great. The downside is that I always have to put everyone elses tube on top of mine and roll them both!
