Well this is where you can hire a content writer to get your content. Copy and pasting others work is frowned up on and will get you banned eventually. You could start out by hiring a writer and getting the work done for you while you read and learn about the niche. Of course if you write your own material you can save lots of money, but it might take you longer to get the content. Just never copy and paste. Learn about the niche and you will soon see how the content will start coming to you.
