Before you start marketing your free ipod product, you need to be an expert in 2 things: marketing and some IT. The login screen and designs issues, how websites should look more attractive, how more customers can be got? These questions need definite answers before you start a referral website. Also the process is much faster and much reliable. The customers have some motivation in the end too. 

Some motivation is always rewarded in form of free gifts. The customers would bring more and more customers for you. The minimum rating requirements would also make it more attractive. The difficult credit rating requirements would often make the customers leave the website without registering.

The marketing system even works better than the telemarketing, in which you keep on calling the customers and the result is a call hang-up. No one likes a call hang up. Try out some better ways and offer a better free Nokia N95 to your customer. This would work 100 times better than the telemarketing. You must also be aware of what referral are you suggesting. People like giving referrals, but hate solicitor calls. 

You are not a solicitor: you are telling them about a new product. The best thing is to make the referral process much simpler and see what benefits are being offered to you. Check out what benefits like a free LCD TV are you offering to other people. Telemarketing doesn’t offer some good motivation in form of any free gifts.
