It's pretty much a do it yourself project. It would be a pretty pricy project for a body shop to tackle - not really that complicated. If the truck hasn't seen much salt and the calipers aren't corroded,a cleanup should be enough. It means a lot of masking, but I'd do it with the whole assembly intact - don't forget to mask off the wheelwell and a pretty good section of the truck body to prevent overspray.
I did my Sonoma with the stock color in Dupont Centari - don't bother with the base clear combination. I did mine 5 years ago, and re-sprayed them this spring - they were in really good condition considering it's my wife's year round driver. I would do both the hub and caliper, but don't bother with the outer edge of the rotor - the heat there will burn the paint off fairly quickly.
I didn't check for a name, but the owner of the yellow SSR who had done his indicated he used high heat paint - that might prevent the outer edge of the rotor from burning paint off, but the caliper and hub on mine didn't need high heaat paint.
I plan to do my yellow SSR the same way when it gets here (sorry if it seems like I'm copying, but I had intended to do it in red also - would do the same on a red or black truck, and probably do the ultraviolet in a nice Tangerine or something.)
Oh yeah - while you're at it, why not clean up and repaint that blue rear shock to red - would look a lot more custom - part of the plan on mine.
I did it all the first time with a baby compresser and an airbrush - this time I still used the airbrush, but am now equipped with a 60 gallon 2 stage compressor - real luxury. I also expect to do a lot of underhood chroming, polishing and painting - should clean up really well lots of billet aluminum to remove and redo.
