Logo Design For Chiropractic Office

I am looking to have a logo created for a Chiropractic Office. I have attached some example logos that I like and may be interested in incorporating into my new company name. I am looking for a logo that will work for Business Cards and web. The finished product must be usable in black and white and color. Final logo will include one file in Adobe Illustrator Format / Photoshop format the other will be PNG for web site. Final image will be selected from atleast 3 different examples with up to 5 changes. Here is the background about the company and what we do. It may give you some ideas about what we are looking for and what services we provide. .. The company will incorporate chiropractic, contemporary medical acupuncture, nutrition and functional endocrinology as an integrated approach to wellness. The endocrinology aspect will analyze saliva hormone levels to assess active hormone levels that are available to be utilized by the tissues, versus total levels available in the blood. Hormone imbalances are complicated and interconnected, manifesting 'symptoms' can appear to be a 'disease process' of one endocrine organ, but actually be due to an alteration in another organ / system / hormone feedback loop. Investigating the patient's lifestyle, physical-, chemical- and emotional-stressors are important factors in determining the primary origin of the complaint. Manual chiropractic medicine includes the treatment of joint-complexes and soft tissues, with techniques to improve joint-motion, and soft tissue consistency and their interaction to the biomechanics of the body. The nervous system is of primary concern for both chiropractic and medical acupuncture, where motor and sensory information is integrated between the brain and the body - both on a (macro) physical, outwardly visable level - such as movement of the body, and on a (micro) visceral, inward level - functioning of the organs and transmission of nerve signals. These components, along with nutritional balance, exercise and rest, as well as emotional (and possibly spiritual) awareness, help contribute to a sense of overall well-being.
