A spin-off for web designers is to offer a landing page creation service. Well optimized landing pages can be the difference between a successful and a failing business. And, as creating the perfect landing page isn’t easy, this is a service many businesses are prepared to pay for. I know people who are earning 6 figures per year and all they do is create landing pages for businesses. There’s serious money to be made.
 @Philip Taylor I was merely using medical science as an example profession. It’s quite obvious that you don’t have any professional courtesy and downplay professions in which you don’t understand. Logo design isn’t just logo design. I don’t know what the profession of a public accountant entails, or a lawyer perhaps, so I’m not going to give advice on matters that I don’t especially have knowledge in.
Now next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
If you don’t mind doing other people’s chores, then TaskRabbit is a great option for making money online. Earn extra income by walking your neighbor’s dog or mowing Mr. Smith’s lawn. It might seem like not the most lucrative option, but the top taskers reportedly earn as much as $7000 a month, making this a full-time way to make money online for some.

More and more companies and startups especially are embracing remote work—where you use online collaboration and communication tools to do your work from wherever you want. And you don’t have to be a 20-something hotshot designer or coder to reap the benefits of working remotely. Many remote positions are for customer support positions or other customer-facing positions that don’t require specialized skill sets.

If you are more confident in your skills, you can also market directly to websites and blogs. You can contact the sites by email to market your services. That will also enable you to select the specific types of sites that you are more comfortable working with. Since there are literally thousands of websites and blogs on the web, the potential market is limitless.
OfferUp.com. If you don't have the energy to hold a yard sale, OfferUp may be the next best, profitable thing. Sell one thing at a time. Take a picture of what you have, put down a price and hopefully somebody nearby will see it online, love it enough to buy it, send you a note and you'll meet – in a public place, OfferUp's website recommends – and you can get your cash for whatever you're selling. Of course, you might ask how this is different than selling on, say, the ever-popular Craigslist. Some users claim that it's an easier site to post on, and members have profiles, so you can rate each other and get a better sense that people are who they say they are, which isn't always the case on Craigslist. Nevertheless, you'd still do well to use common sense and buy and sell OfferUp items in public places rather than at someone's home or in the dark woods.
Take surveys. You can earn $50 to $100 per month in cash and products by taking online surveys. Find survey sites by searching for “paid survey sites” online. Sign up for several survey sites to increase your chances of being selected for higher-paying surveys. Register with an email address, and check your email often so you can respond quickly to survey offers.
Need more ideas on how to make money online? Another strategy is using webinars to market your product, service, or course. I’ve done webinars to promote my financial planning practice and to drum up interest in my online course for financial advisors. With a webinar, you’re basically offering a lot of tips and advice for free — usually in a live format. At the end though, you pitch your paid product or service with the goal of securing a few deals.
