You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low. You don't need to invest lots of money to make this happen, but you do need to invest lots of time, not only in writing the ebooks, but in marketing them as well.
There are many ways in which you can make money with WordPress. Creating a website for the purposes of promoting a business or selling goods through an online store is one such way. Monetizing a blog with display ads is another. While there are other ways in which you can use your WordPress site to make money, perhaps one of the easiest ones to get started with is affiliate marketing.
Retain some control. If you upload photos of yourself, or friends/family with consent, it's worth going for the 'rights managed' licence option – otherwise you'll have little to no control over how your images are used (eg, you could star in an ad for haemorrhoid cream). See Alamy's page on understanding stock image licensing for more on the different types of licences.
As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
It’s extremely WordPress-friendly. As you’ll soon see, it’s very easy to add Amazon affiliate links to WordPress.

House sit if you have neighbors who go on vacation. Water their plants, take out the trash, check the mail, and keep an eye on things. They may ask you to visit 1 to 2 times a day or even spend the night at their house so it doesn’t look empty and prevents burglary. Follow all of your neighbor’s rules and instructions and always lock up the house when you leave to keep it safe.
Rake yards in autumn if you live where leaves fall. Grab a rake and a few large trash bags and go from house to house offering your services. Ask your neighbors what areas of their lawn they want raked and where you should put the leaves, like on the curb for collection or dumped in a wooded area behind their house. Rake leaves into a large pile, then stuff them into a trash bag and tie it closed.
Consider selling in lots. A lot is a collection of similar items that is sold in a group. For example, if you have a collection of books, magazines or similar pieces of jewelry, consider selling them all at once in a lot. You many not make as much money as you would have if you sold each item separately. However, the items will likely sell more quickly in a lot than they would individually.
It has universal appeal. Unlike some types of marketing that work better for certain segments than others, affiliate marketing is really something that anyone can use on their WordPress site or e-commerce store. With millions of products available and categories covering a wide spectrum, you’re bound to find more than enough products worth promoting.
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
