Combining Files to Form a Consolidated Version

My filing system is in a state of chaos. Over the past few years, because of travels and other reasons, I have copied my files onto a number of drives with the result that I have a lot of duplications, to the extent that many files may appear in some 20 different locations and subdirectories. This situation is becoming totally unworkable. I have all my hard drives with me in Manila, the Philippines. I need someone to combine all these files by getting rid of all the duplications to arrive at a ccomplete consolidated version. It will be quite impossible if one were to work on the files on a manual basis. As there are quite a number of programs available in getting rid of duplicated files, I believe the task may be manageable by using an appropriate program to assist. I am wondering if someone is able to provide me with the complete consolidated version in about one week. I have earmarked a budget of A$ 100 for the task. As I am physically in Makati, Manila at the moment I would prefer someone from Manila to help out. Interested applicants should have experience in performing similar tasks before.
