Honestly, for the problem you have I cannot see how one of those people could possibly be of any help to you. If you found one that would actually agree to touch you, I would run as fast as I could away from them because curvature of the spine is a surgical thing not a bone cracking thing and I just fear for anyone that outs their health in the hands of a chiropractor.
You need to see an orthopedic spine surgeon and see what they say for you to do. Yes, all doctors and also all chiropractors are in business to make money but imo doctors are also in the business of fixing and hopng for final results wheras chiropractors are built on prolonged or even lifetime visits.
Please visit Spineuniverse.Com to research for yourself. This website has both doctors and chiropractors on it, that site will answer 90% of all the questions you have. Scoliosis is a very hard thing to live with but you can do it with the proper treatment and imo chiropractic is absolutly the wrong form of treatment.
Hope this helps,
