Online sites like Etsy and ArtFire are platforms that make it extremely easy for crafters who can produce a steady supply of quality handmade items, like crocheted blankets or unique painted glassware. Startup costs are extremely low if you purchase your materials in bulk from a craft supplier, and if you can turn around orders quickly, you'll be making a profit in no time at all. It's even possible to turn your store into a full-time gig.
Market your talents to building contractors. People purchasing new homes can often be overwhelmed with the choices and possibilities in home decorating. Design some questionnaires for each major element and each major room in the house. Find out how the homeowner will use the home--are there children? Pets? Does the woman of the house wear high heels? Do the home's residents neglect to remove shoes? How will each room be used? Where might task lighting and ambient lighting be most appropriate?
To locate sites that might be interested in your content, e-mail other website owners in your industry–be sure to choose sites that receive attention and visits from your target market–and invite them to use your article on their site or in their newsletter at absolutely no cost. Many site owners need fresh content, so they’ll be more than happy to post your articles–and it won’t be long before those articles start driving traffic back to your site.
Though certainly not for everyone, recycling the containers from products left strewn around on the ground can become a surprisingly decent side business idea if you put in the time. Attending events like street fairs and outdoor concerts can be a great starting place. Put on a clean shirt, jeans, apply your sunscreen, grab a cheap pick-up tool like this one, sturdy plastic bags, and you can sell them for upwards of $4.00/pound on eBay.
Live in a destination where travelers frequently visit? If you love meeting new people from around the world and also love the city you live in, starting your own local tour company is arguably the best business idea that will give you both of those perks. Take a unique spin on your local tour business like Erik from Vantigo. He was starting his VW van tour business in San Francisco as just a side business idea while he was still working a full-time job, and grew it to being a sustainable source of full-time income before quitting—now he's running a multiple van tour company on the back of what originally began as a crazy side business idea.
Start with a very good checkout flow / payment gateway right from the start. I’ve spent too much time thinking I could whack some checkout together with PayPal and a (typical Dutch) bank payment system, but ended up with a lot of coding and hacking into WordPress to make it all happen. Actually, the right checkout still hasn’t been implemented #@!^&*^
So, I put together a free master course for you to take that spreads out all of the work involved in starting a blog, into a series of action-packed lessons. My free course breaks the entire process of starting a blog down into an incredibly simple 7-day process for going from 0 to publishing (and promoting) your first blog post in just 1 week. I can't recommend it enough.
