Data extraction from social sites

Hello, I am looking to create a web site where the user will login and create their account. They can use LinkedIn , FaceBook , twitter and Instagram to update their profile with information in online sites. Then they will update is/modify it . We are looking to get whatever data possible to extract using their public APIs. Looking for person to get these information from these three sites and update their profile. We expect to get their address, their qualifications, their experience details, their credentials, certificates, recommendations, social activities and profile photo. Also, their special interests, published papers and/or contributions. Whatever can add to their profile, are needed. We intent to create a larger profile of the person using these details. Any one interested, let me know. This could be a starting project which may bring up a wider project. Looking forward to hear from you. Regards,
