Make modifications to a flash application

Important: I only have the SWF file, which means that you should be able to decompile Flash files to complete this project. The application isn't very complex(it's a logo maker app), and the modifications required are quite simple: - change some texts; - remove the fotter; - change some links; - also, it seems the app loads data from an external server. I need such data to be stored and opened locally. Budget is $50,00 and the deadline to complete the project can be around 7 days.
