AVS (Adult Video Script) Modification

I have purchased the following script: [login to view URL] with the video grabber plugin. Front-end will eventually be provided, this project concerns the backend of the script and implementing the design that is going to be given. The functionality I require: - To be able to embed videos from most of the major free porn tube online sites (redtube, tube8, youporn, tnaflix, etc.) - To be able to grab them automatically (The AVS script does this) - To be able to play random videos (Separate section of site) - To be able to play random videos based on categories (filters) selected or unselected. (Another separate section of site) - Once random videos are played, ensure that this video will not be played again unless user chooses to favorite - Favorite and rating system (should be included in AVS script) - Make sure everything runs smoothly with testing. Please send me any questions if you have any. Please provide your link with past experience and portfolios as well. Have a great day!
