Themes WordPress scraper and format

We require a WordPress plugin made that will scrape in iPhone themes / wallpapers and android themes / wallpapers from other sites. It will scrape in the image of the display image of the theme, any details about the theme, and the download of the theme (which will be uploaded to my server). You will also need to make some alterations to my theme – nothing major. I want users to be able to rate the themes. The users will also be able to upload their own themes and wallpapers. The format will be simple be custom. I want an A-z for each category, which should be automated based on the starting letter of the theme. Your plugin should also be compatible for other templates for in the situation that we change the theme. I would like this task completing fast, and good communication.
