Help us get this trash compactor puppy back on his feet!

Hi everyone! This morning, my husband received a courtesy call from a resident in our apartment complex that a dog had been dumped in the trash compactor on site. We rushed down immediately to help out, and Brandon was able to recover him safely. Unfortunately, it appears his rear end is in need of medical attention, as he can walk, but with great difficulty. I'm sure this will involve X-rays and potentially surgery. He's not in any pain, but we want to get this sweet boy the medical attention he needs and the care he deserves. He's a gentle and mild-mannered dog, who doesn't appear to be very old at all. He does need to be neutered and undoubtedly will need his shots and worming treatment. We're willing to help him out, but we know it will involve some hefty veterinary bills. Any help would be greatly appreciated, and I know this baby will be forever grateful. Thank you so, so much!
