Some people can weld, if you make, and hand them the parts.
A true welder/ fabricator has a vision and takes avaliable materials and produces and end result.
Reminds me of the backyard of my first house, had a small river like that running directly behind my property and a private golf course on the opposite side. Loved that yard, house was small, only about 700 sf, but was only supposed to be myself and the wife and 2 dogs. Then her kids, their kids, and pets moved in. Yeah....about that.
