I am a bit confused by your post. You want to fix the pipes until you can get a plumber. You can likely get a plumber within a week or two at most, so what is the emergency? From your post, it sounds like the pipes have been leaking for a long time. In part of your post, it sounds like you want to do the work yourself, but if that is the case, why do you plan to call a plumber? If all you want to do is make a temporary patch, there are various types of plumbing epoxy that can probably hold for a week or two which should give you time to hire a plumber to replace the pipe.
