Strings are supposed to "rest" in the cradle of the saddle with no added pressure pushing down on the string due to incorrect alignment. Level saddles will keep the "point of string contact" correctly, otherwise many issues can pop up, including pre-mature string breakage.
I'd rather have the guitar on the bench in front of me and measure the action and neck relief to have a more full piture of the setup. I don't see anything horribly wrong with it though it is higher than I would expect. If the guitar plays well and there are no problems, I think you can happily leave it without any worries. However, you can of course lower the saddles and maintain the string action by raising the entire bridge from the two trem mounting posts. (You may have to adjust the tremolo claw/springs to keep the bridge plate parallel to the guitar top).
Absolutely, they do great work and their rates are very affordable.
But- if it's just for a regular set up (and you don't need fret work, etc.) you can learn to do this yourself, or find a good tech in your neck of the woods. (Teach a man to fish, and all.)
