226955 Unique url download

Hello Greentech, You bidded on my project recently for $100 to build a unique url download script and examine a music search script for me. The person i chose did not deliver, so I would like for you to take on this project. However, i only need you to do the unique url script. This script will generate a unique download link for the file i sell on my website. The file will be located in a hidden directory and will not be called by http. Please let me know how much you will charge just for that project and how long it will tke
