But be wary. Food service—even a delivery service, which is the most likely scenario for home bakers, as opposed to setting up a storefront—comes with built-in risks. Prepare yourself, and read up on your local insurance requirements. And don’t be afraid to start out by making just one or two really great treats. Consistency is more important than variety in the baking business.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
I have another to add to your list that’s almost as easy to do as going for a daily walk! Clean up litter outside commercial properties for property management companies. The work is done on foot using simple hand tools. I started this as a side gig in 1981 and grew it into a profitable full-time business that I continue to operate today. I share my experience in my book, Cleanlots, and offer free support.
I recently started working in network marketing with a natural hair care line. It has transformed my life, by giving me my confidence back. I was losing my hair and I didn’t know what to do. I’d been to the Dr and told it wasn’t a thyroid issue, but they couldn’t tell me what WAS causing it. My good friend introduced me to these amazing products, that in a matter of months changed my life. My husband is now using the products for his “gaining face” (not receding hairline) issue. Lol.
A blog highlights your technical ability and showcases your ability to write blog posts. Your blog can be about different topics than those you write about for your clients. In fact, it should be on a topic that interests you. Visitors will see that you can not only write, but you can also build an online community. A good blog has the potential to earn you many referrals for more clients.
Consider your expertise. If you take the time to reflect on your experiences, you will realize that you have more knowledge about which to write than you might think. Begin by listing three assets that define you, such as your profession, a special hobby or a personality trait. Next, list three things that inspire you, such as religion, education or charity. Finally, list three of your dreams, such as getting married, traveling or spending more time with your children. These three lists should give you many ideas of topics about which you can write.
Once a pie-in-the-sky idea, home businesses are a reality for millions today. It's easier and more affordable than ever to build a home-based career. This doesn't mean that profits will be automatic, immediate, or easy to achieve, but you can be a successful home-based entrepreneur if you have the desire, a plan, and you're willing to put in the work.
"Many people think they have a great idea and jump into launching their business without thinking through who their customers will be, or why these people should want to buy from or hire them," Desaulniers said. "Second, you need to clarify why you want to work with these customers – do you have a passion for making people's lives easier? Or enjoy creating art to bring color to their world? Identifying these answers helps clarify your mission. Third, you want to define how you will provide this value to your customer and how to communicate that value in a way that they are willing to pay."
All great ideas! Not sure if you left multi-level marketing off on purpose, but I’ve recently started taking a nutritional supplement called Thrive, and due to the amazing results (tons of energy, great sleep, calming of aches and pains, etc.) I’ve started working as a promoter. There is absolutely no requirement to pay anything to sign up, you don’t even have to stock the product, it is a cloud-based business where the customers order online and receive the product directly from the company. If you get two people to sign up with autoship, you get your product free. Even if you pay for the product it is only about $5 a day, less than a cup of coffee in the U.S. So far I’ve been really impressed.
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
