How about this?
You might think the price is high but consider all the work you now DO NOT have to do. Just toss it under the LASER and start burning away.
Price your bid by unit and give a break after 5k units IF ordered all at once.
Tell them you got better pricing on the .032" material if they should ask and you’re passing the savings on in your bid. But if they want .025" you can give them that at a slightly higher price.
