looks like an easy dent to pull to me, most any body shop should be able to take care of that and you may be able to push some out on your own just get in the trunk and give it a good push. One thing to make sure they dont do is drill holes and use a slide hammer to pull the dent, this is ok as long as they weld in the holes but most just bondo over them and then you have a good place for rust later on
