Topic: Invest Or Not

I am a metal artist. I use a very good powder coater but have been thinking about building and buying the equipment to do my own. The problem I'm tring to overcome is, as a rule the coater does a very good job, but on occasion they miss handle a piece and it is ruined. All my products are clear coated, and as my luck has it the piece that usually gets damaged is one thats a custom order. So my question is what would a good system consist of and how can I keep it affordable? The largest work Ive done so far was 8 feet long by 4 feet high and 5 inch thick, a multi layered mountain,lake forest, Elk scene.
