Domain Name Service

I see that lot of domain names (ex:jbroot.com) have been bought by so called "domain players" and sold at very huge price. The above mentioned domain name is not hot in search trends, then how come it is priced so high? I am planning to suggest domain names (not automated one) but don't want to sell it to guys who are making already a lot in this business. Is there any way that i can suggest domain names to individuals so that they can be benefited and i can earn few dollars? I cannot buy and stack them up and affiliate is just one time payment for one customer that i send.
