Many people fancy themselves as designers. If you have a unique idea for a new product then it may be time to get it designed. This can be a long process involving prototypes, discussions with factories, package design, and much more. However, the profits once the product is on the market could be substantial. And remember, with Amazon FBA, your products can all be stored and shipped by Amazon, giving you time to think up your next invention.

Great article, I have tried a few over the years. I had a side business cleaning offices for years. It did great, but I hated never being able to take more than 3-4 days vacation, so I eventually gave up. I tried MTurk, but if you multiplied my earnings on an hourly basis, it was a little over $6/hr. My blog is much worse, probably less than $0.25/hr.
