If you're tired of doing research, or not just fond of it.. There's a bit "sneakier" way to get things done. I'm talking about PLR products. PLR stands for “Private Label Rights”. You can edit them, sell them and claim ownership to the product.
Most PLR products comes with everything you need. Ebook, covers, articles. Even sales letters, so it's easy to start selling them. However, I do recommend that you alter the information within. Re-write the content. Use your own words.
Here's a few links for PLR stores.
