Edit Flash File to Read XML File List

I would like my current Flash Card program edited. Currently, I have an .swf flash file that prompts a user to upload an XML file. The flash file reads the contents of the uploaded XML file (a simple list of words) and proceeds to function as designed. We need this behavior changed so that instead of the flash file prompting a user to upload an XML file, it will read a list of XML files which are stored in the same directory on the web server as the .swf file is stored and will then prompt the user to select one of those files. The menu to select a file should not display the XML extension - it should just display the name of the file. Also, there is currently a "timing" feature in the file that allows the user to select how fast the cards are changed. There doesn't seem to be a big difference between the shortest and longest setting. So I want to make those a bigger span of time. The faster one faster - the slower one slower. I have attached all the files I have for it - the source and others. Please make sure to ask me questions. I will make my decision based on cost, feedback and communication.
