You have sent me full colour images. If you want to print them as they are, they should be printed on coroplast signs using full colour digital print:
50pcs 24″x18″x4mm coroplast signs with full colour print on both sides are $6.20/sign. Metal frames are $1/ea extra. See our price list here: https://www.lawnbagsigns.com/coroplast-signs-full-colour.php
If you want to rework the design making it 1-2-3 solid (no shades) colour image, 50pcs 24″x20″ white lawn bag signs with one colour print on both sides are $4.20/sign. Metal frames ARE included in the price. I can give you much better price if you order 100 signs with the same design, which is $2.50/sign. Design rework is extra depending on the number of design colours.
