Adding to Price for Certain Color Options and Sizes


#1

I have a vinyl decal business, and am beginning work on my website. I need to be able to charge more for Coral (and later, other colors such as glitters). Here is a link to one of my items I need to do this with:

I need to set price increases like this:
(1) 2.5 inches through 4 inches, outer portion: + 1.00
(1a) 2.5 inches through 4 inches, inner (monogram) portion: + .50
(2) 5 to 7 inches, outer portion: + 1.50
(2a) 5 to 7 inches, inner (monogram) portion: +.75
(3) 8 to 10 inches, outer portion: + 2.00
(3a) 8 to 10 inches, inner (monogram) portion: + 1.00
(4) 11 to 12 inches, outer portion: + 3.00
(4a) 11 to 12 inches, inner (monogram) portion: + 1.50

Thank you in advance if you can assist.
