First: Congratulations on bringing a quality design to market.
Second: You are selling to cheaply.
How much time goes into each item? 2-3 hours?
The best streamlining I could think about is loosing the trimming process altogether leaving you the shiny aluminium bits themselves. Why would you cover them?
Your process of trimming is simular to high end Italian furniture, but those are 10 times the price.
