EDIT: If the answer is you want to do it yourself, do you want to invest in buying a polishing machine or do you want to try it by hand? If you want to do it by hand, a better bet than Scratch-X is probably going to be Meguiar's Ultimate Compound with terry cotton or microfiber applicator. If the scratches are gone but the gloss isn't to your liking, follow up with Ultimate Polish.
Then please follow that with some sort of wax to make future bug removal easier, and do it on a regular basis before the bugs etch into the surface. A rinseless (spray) or waterless wash can also be found locally and will make it easier to accomplish the bug cleaning.
