how can get referrals?

When you're trying to get more referrals, you're much more likely to be able to get people to sign up if you're able to show them some payment proofs that you've got from the various websites that you use. Your family and friends are a good place to start, as you'd be able to talk to them about the websites and would be able to show them directly what can be done on them, so they'd be more likely to believe you about it than if you were to just post links on forums where people don't know exactly who you are.

You can rent a referrals from the site you joined, you can give your referral link to your family and friends. And you can also use your facebook account to promote you referral links aside of making your own website.

To build your own web site and recommend to others,I think this is most efficient way

if you want to get referrals just send your referral link to your friends or make a blog site then post all your referral link there. Don't forget to put your payment proof so that you can convince them to join.

Add as many friends as you can in all social networking sites and send them your referral links.
