Powder Coating Question?

I know this thread is for paint and body work but I was wondering if any one knows how much powder coating i would need to order if i want to get my upper control arms, lower control arms, KP 6-link cantilever set up with the watts link, front sway bar, bag cups for the front, all four rotors and all four calipers. The truck is a 2000 silverado single cab, any help would be appreciated.
 
Thank you.
