Data Extractor from websites

We need the Data Extractor that can be customized for a various data to be extracted from websites, including emails, links, contact informations, images, user-defined data, etc (must be very customizable). Also multithreaded script/software is required (more connections at once while collecting the data). The project needs to be of the high quality and stability, so please don't bid if you haven't done such things before. And also, please place the word notabot when bidding to distinguish between the automated biddings and the people who actually read the project description. The project is intended to be a unique all-in-one software able to extract any kind of data and will be reselled, so we need the complete source code and copyrights. Thank you and happy biddings.
