Most of the time we do not get knocks from clients. For this we can check our status in the search bar. Search yourself in the services required search bar as like you are a buyer. Search with the keywords that you used in your profile. Then you will find other people gives with the same keywords. Now it's your turn to research on this. Study properly their profiles and try to update your profile. Do it again and again and you will find a better result. Best wishes for all.
