Like writing (above) transcription is another type of work that often equals a full-time income. However, there are lots of sites that accept beginners that don't pay very much for the audio transcribed. While a professional transcriber may not bother with the sites below, someone without the skill to be a professional could use them here and there for some quick extra cash:
Where Indeed excels at finding job postings across the web and acting as a search crawler for employment, maybe a full-fledged career is too big of a commitment at this point in your life. Elance is a site to find freelance work of all types. I’ve used it for quick writing, editing, copywriting, resume building, and other odd jobs and temp gigs. The experience has been great.
There are loads of resources for making money online as an affiliate. You could source products from ClickBank, Commission Junction, Rakuten Marketing, Share-a-Sale, Impact Radius and many others. Plus, many of the larger companies have their own affiliate programs as well. Do your due diligence and find the right company with a relevant product or service to your audience that you can sell as an affiliate.
Multi-vendor marketplaces, like ThemeForest, can be very successful. Chose a niche and create a vendor website for it. Your marketplace could be anything, from a platform for local artists to sell their work on, to an online digital product store. Once set up, invite people in that industry to sell their products on your site. You take a percentage of their profits when items sell.
Mow lawns or plow driveways. If you’re willing to mow yards or shovel or plow snow in the winter, you could easily start your own snow removal and lawn mowing business on the side. While you can usually find work by reaching out to your local community via word-of-mouth, flyers, or online message boards, the website Plowz & Mowz allows you to set up an online profile and reach more customers in your area.
You can also market your ebook on your own website or blog, particularly if the site gets good traffic. Still another method is affiliate marketing. You can offer to pay sites related to your ebook a percentage of the sale price – say, anywhere between 20% and 50% – for them to post an ad or linked article for your book on their site. This could enable you to market your ebook on multiple platforms for greater market exposure.
