Because smartphones are everywhere, the demand for new and creative apps is increasing in popularity more than ever before. Between Google’s Android and Apple’s iPhone market, people are using countless apps everyday. And, most of them are selling right and left. Taking the time to develop and sell a smartphone app may be worth your while since it’s a very lucrative way to earn money online. The apps cost almost nothing to actually develop and don’t involve any shipping or storage costs, which works to expand your overall profit margin. Well performing apps can make thousands in ad revenue each month for their creators, making them another great passive income strategy.

I have a friend that is the city manager of a town of about 25,000 where his main task is processing requests for building permits. Actually a volunteer-type job, no salary. But he makes a bunch of contacts every day, and his address book is huge. So he is busy all year except the Holidays. To fill in this time he started a Christmas tree lighting service (houses, lawn ornaments, etc.). In this 3-month period he makes enough to keep him going the rest of the year.
This site is EXACTLY what I was looking for. I am a fit and frisky 56 y.o. single dad working 2 jobs, with an unquenchable thirst for learning new things. I’ve been surreptitiously studying the New Thought writers (from Atkinson to Proctor right up to some of the really sharp, young people creating YouTube videos). I think I’m getting a grip on the self-motivation and metaphysics of the whole thing, but am too scattered to decide exactly what kind of business to start! many of your 27 ideas I have some familiarity with (one of my old army buddies got me in to Bombardier Transport in early 2011 for 3 months to help meet a deadline on some tech pubs…it was a lot of fun! I was told I’m a natural, but could not find any more jobs in that sector….Oy Gevalt). Anyway, thank you so much for this site! I can give you a progress report every few months or so (including showing you how any websites I may be creating are doing). Happy New Year!
... 'Lifestyle' HBB can be either 'growth-rejecting' or 'growth-enthusiastic' but Lewis (2008) argues that actually they should be seen as engaging in a 'freestyle' modus operandi as lifestyle is not something accommodated by the businesses but is rather a conditioning factor in the business operations. It appears from the research that HBB set up by women are more likely to be financially marginal as they are more likely to be operated parttime , and be started because of circumstances rather than their entrepreneurial skill sets (Thompson, Jones-Evans, & Kwong, 2009). Nevertheless HBB are a popular choice for women with family obligations as even with less financial success, role conflict between work and family tends to be lessened (Loscocco & SmithHunter, 2004). ...
You know this one already. You include links to products you are promoting as an affiliate and every time somebody buys the product, you get a commission. With a blog, you can integrate advertising with content to make it even more likely you’ll get the sale. For example, you could do a product review—which is useful content—and then include a link to buy the product under an affiliate link.
I like these ideas! Besides being good ideas in themselves, they stimulate MORE ideas! Some of them reminded me of something I was reading about called Craigslist arbitrage – buying low and selling high on craigslist, kind of like the first part of the old Oregon Trail game, but with washers and dryers and bicycles instead of cases of crackers and horses. Sounds like fun!  Anyway, that one about the pooper-scooper business, that works, I know because I was quite successful in the pooper-scooper service I started back in 1988! I’ve been in the industry for 25 years now, though I don’t go out and scoop any more.

... To illustrate, three empirical studies are described, though this is not exhaustive. First, Thompson et al. (2009) use Global Entrepreneurship Monitor data, basing their measurement of HBB on nascent and start-up activities in the home. Elsewhere, Felstead et al. (2000) base their study on the 1998 Labour Force Survey that explores those who work mainly, sometimes or partially at home (both employed and self-employed), thus not separating employment and self-employment status. ...
When one of your customers makes a purchase, you purchase the product from a third-party company (the drop shipper, usually a manufacturer or wholesaler) for a lower price. This process is as simple as forwarding the order from your customer, a process that can actually be completely automated. (Remember you don't have any risk here of buying inventory because the sale has already been made).
