Python script to randomize PHP script

I want Python script (I will run this on Windows) which will randomize name of the files and directories (and of course change references inside each PHP, CSS and JS files) so all files and directories I mark bellow in red will have new name and length (see attached file) I believe you can use RND function to generate random names So for example directory named cache will be: xdftrjslks and file: [login to view URL] will be [login to view URL] I prefer random length of names and random text names (let's say in range 1 to 14) Of course you can only use letters, digits and special marks which is permissible on web server (so ? or * it's not good of course) Folder SOURCE and its contents will be reference for generating new script in folder named NEW I will send complete script if you pickup this task. I will pay 30$ for this easy task
