Anyone who owns a blog or website can join the Amazon Associates program. Basically, you include links on your page that will direct customers to Amazon product pages. If customers use a link on your page and buy something in a qualifying sale, you can earn from 4-10 percent. You can do your part to earn more money by giving people an incentive to click on the links. For example, if you have a blog about pet care, you can link it to pet care supplies on Amazon.
Big companies are generally (or at least should be) flexible if you want to work from home a few days a week. But if you want to do it full-time, smaller companies can be a better bet, because your working remotely can help them save on office space. You can probably find lots of startups or small businesses looking for tech help who have the resources to pay your salary, but not to relocate you or pay for additional office space.
Believe it or not, you might already have most of an ebook written already. If you are already making money with a blog, those blog posts could be turned into an ebook with some editing. Simply collect relevant blog posts into an order that makes sense, make any needed edits so that references that aren’t relevant are taken out, and add an introduction and conclusion, and you’re done. Any blog posts you use should cover the same or related topics and work well together.
