2 years thinking about it?
You're approaching it the wrong way.
Just start something. This is not a business where a long perfectly written business plan will do you any good.
Just start something. Work at it hard.
Just start something. Measure its success carefully then try something else slightly different that includes the successful bits.
Just start something. Try different approaches on different sites to figure which things you are good at and also are happy to do day in and day out in a grinding way that will make you money.

My advice to anyone considering this biz is - don't leave your day job until you just don't have time for it anymore! Ideally this will overlap with the start of income.
