anatomy illustrations of the spinal muscles

i need to show how certain spinal muscles in the cervical and thoracic spine become imbalanced together with the corresponding misaligned vertebra/bones when they become misaligned as described in chiropractic atlas subluxation theory. Ie when the atlas bone becomes misaligned it starts spinal muscle imbalance from the top down starting with the head (heavy bowling ball head) to the suboccipitals, trapezius, rhomboids, hips. Imbalanced muscles are almost never shown together with their corresponding misaligned vertebrae/bones. They mostly show the skeletal structure alone in misalignement. I want to show both muscles and bones together. As for pay i will pay more once we are on the same page as i've already spent a lot of money with little results. However, once we are both in agreement as to what i'm looking for i am willing to pay much more. To give you an idea. I've spent several hundred dollars on the internet with illustrators and gotten a few drawings without them understanding my concept while it took just five minutes with a high school student in person for her to immediately grasp where i was coming from. I need this kind of collaboration to move forward. I don't need super professional graphics initially. These illustrations must be simple enough for a child to understand and can just be simple sketches to start with for the illustrator and myself to understand what i'm trying to convey
