Why do your prints look different from the images on your screen

Your monitor is only accurate if you have calibrated it using a monitor calibrator. These are relatively inexpensive devices now and are easy to use. Adobe Gamma comes packaged with Photoshop and is relatively easy to use. When you adjust the image colors on a calibrated screen you will be confident that it actually needs adjusting. A good print service provider should now be able to provide you with prints that are very similar to the images that appear on your screen.
