Hi Yogesh
You can source profiles from Google Search. And it depends on the keywords choosen by you.
You can give the keywords as " Free Resume search" OR "Free Resumes" which will take you directly to the websites(Unpaid), from where you can source profiles.
Better you search for some freesites wherein you dont have to pay for that and then access them for the profiles.
I believe this kind will not give you right profiles.
Let me know is you have any queries.
