We need an aggregate social data site. Something like entelo.com or talentbin.com. First read the detailed RFP which is attached. Then make an account at entelo.com and/or talentbin.com. I am not sure if entelo will let you sign up but I have signed up for free at talentbin.com and it works.
Regarding scraping from LinkedIn, I will first hear from you and then I think I may have something which will help you with scraping data from there.
Please view the attached RFP and the two sites and send me your questions and comments.
This is an ongoing long term project and I need a good efficient trustable team which can do the job and is a serious bidder.
So please only bid if you are serious. Also if there is some part of the job which you think is not possible or can be done in a later stage of the project, feel free to mention so.
