You can't guess when it comes to business, you need to have a plan that is adaptable based on many factors (the economy, tech developments and a host of other things).
Before you even think of starting any business you must learn to find and use resources. Without that skill set you will fail.
I wasn't asking if you were comfortable with the people you are thinking of starting a business with. I was asking if you think vague phrases and time frames without viable research and stats to back it up sound like a good foundation to put your idea on.
My point was before you start "getting in to it" you need to have a plan that is not made on guesses and what other people tell you. You need to have a solid plan based on facts, figures, research and defined roles.
