This is a question often asked on this forum.You are asking us to tell you how to level your home by just the few words you wrote here. This is a large job that has to be seen to give any advise on. We don't know if the original supports will work ,or if you need to take them out and use a new foundation approach. To many things to consider. Think of it this way, if you can't find it in a good home repair book,the normal homeowner does'nt need to attempt this repair. I understand being on a fixed income but,you need someone who is capable of handling this job in your city. I think everyone alse will agree to this also. Sorry, Ron J.
