Ouch! $2k into a ZZ? If that didn't include cases that's nuts, even in today's economy.
I remember hearing about this kid that used to drive a truck for Mark Wilson working his way through trade school. He got pretty good at it and started building some things for Mark, like this nifty little Choo Choo Train. . . his name was John Gaughan. But John studied how to make magic with legendary builders of the 50s & 60s.
My point being that one really needs to know the skills of a high end cabinet craftsman as well as engineering, welding, auto body work and mold making before they become a part of the magic making market and on top of all that they need to understand the art of genuine deception based on theatrical setting, the use of fabrics, paint/finishing work and so much more.
But we all have to start somewhere, so take your time, listen to those with greater experience than you when it comes to making cuts, hiding hinge work, etc. Magic can be amazingly crude and still work, trust me.
