Youtube search crawler + search result saver

-Private research project- Need software with very simple GUI that does the following: Input: Multiple Youtube search result URLs Example: [login to view URL] Function: 1.) Programm opens all URLs in a browser (only Waterfox support necessary) 2.) Scrolls down until all search results are loaded. 3.) Saves all results, thumbnails, and links (links to video and channel) on the local harddrive (in a subfolder of the program) and creates a (maybe HTML) file for opening the list in the browser at a later time. One file for each input link. 4.) Refreshes pages after a set number of minutes (which can be adjusted in the GUI) 5.) Automatically repeats step 2-4 and adds new results to the previous local file. (Doesn´t need to be able to detect which results are already saved and which are new. Duplicate saves are okay.) 6.) The local file should look like a long search result list if opened. Links should be clickable, same as on Youtube. Also necessary: Start and Stop button/ Remove and add links in GUI. Please tell me what you would charge for creating this software.
