Selling a product or service is one of the best ways to make a lot of money online. You can become a millionaire/billionaire with this way of making money. But you’ll need to create and market your own product or service.

Level

It’s pretty hard to start an internet business selling a product or a service on the internet, it’s one of the toughest out there because you’ll have to do all the work. But you can make a fortune if you succeed.

Amount of money to be made

From zero to a billion dollars. Really, it depends on the product or service you sell. If you have a new idea that doesn’t exist and everybody likes you can make a lot of money, but if you go into a really competitive market you’ll have a much harder time to get rich.

Amount of work

A lot, you’ll need to develop a product or service, start a business, find a way to promote it and then sell it. It takes a lot of work, but this way of making money is what made the young college students, housemoms and housefathers millionaires.

Skills

You’ll need business skills to market your business, to keep your business online and to sell your stuff. There is a lot of knowledge you will need for this, but there’s a lot you can learn on the internet about it.

Time span

This might take you a couple of months full time to set up, it’s a lot of work, but once you’re successful you will make a lot of money. And believe me there’s nothing better then earning money with something you created yourself from the ground up.
