How does one start selling domain names?

[King Belieal]

I don't even have an idea how this business works but I use to see people advertising for people to buy domain names.

What does it take for someone to sell domain names? How does the business work?

You can either start a domain reseller business or start selling pre-registered domains.

How would one source for domains that he can resell? What is the profit margins typically for that kind of business?
