I actually research as much as possible. On top of that, I also ordered a book which the author will email the updates for FREE by purchasing it. You have to show proof though. Amazon have her book. It lists some sites that pay writers.
On top of that, I also use free online resources to find sites and companies that do hire telecommuters/freelancers. I am, as of now, printing out a free ebook of places that we can make money working at home. I can’t wait to see all of it. 🙂
