You can only blame yourself for your bad luck, but I have a suggestion: go to a typing and copying shop near your school. They usually have more or less manuscripts of other graduates' papers or revisions. You can ask them to help you, and then make some changes to the beginning, end and order yourself, or ask them to help you revise it directly. Choose a topic from several similar papers and use the beginning and end of other different papers. This way, you don't have to worry about "collisions". Practice has proved that this is feasible, and you don't have to worry about being cheated of a lot of money. It's very cost-effective.
