This is how many successful businesses operate in the "atoms" world.
You take a product or service that's already popular and has a solid channel for distribution, you transform it or add additional value to it and sell it for a profit.
Think about a $8 precut, packaged pineapple at the grocery store.
Once you get your business going and get additional funding or generate cash flow, you can invest in getting rid of some of the middlemen so that you can take their profits too (start growing your own pineapples).
Sounds pretty straightforward, but the selling part is the difficult one.
