the Printing Service uses. If you use Costco, for example, Dry Creek Photo has the profiles for the printers used in specific Costco locations. You will then need to tell the printing service to print the image as is. They should not make any adjustments.
Which printing service do you recommend?
Also, I just brought a monitor calibrator, Pantone Huey Pro. I would like to know what profile should I attach to my jpeg file before I send it to a photo service site?
