Magic does work and the thing about it is that it only works with belief, people tend to cast spells with doubt saying they will believe when it works but by doing that they are dooming the spell.
People get the wrong idea about how magic works too, the money spell won't give you a lottery win, it gives people opportunities to make money, however there are specific spells for lottery & bingo type wins. I would suggest reading through some Carl Nagel books which can be found on Scribd.com.
As for healing, I have never came across a spell that will heal someone from an illness or disability, mainly because I haven't went indepth with those type of spells. To me when casting healing spells it is always best to have them deal with creating the best conditions for medicines and treatments to work, it has a higher success rate.
There are many spells on this site that deal with what your looking for, have a look through and see if any of them feel good to you. There is a good money spell in the Carl Nagel books which I have used, brought me small wins on the Lotto in the UK, nothing major just a few wins under $50 over a series of weeks but that was good enough for me.
