I salute you for your "foolishness" and "Solution Management" ability.
Without being a fool and finding a solution, nothing that you say is possible. Risk taking is another part of big pictures for those who want to operate their business. If Risk is not something that you like, don't even try.
My general observation is, many people will throw their towel and give up before they even exhausted all their solution, some even too lazy to find the solution.
I can't stress enough that, it is entirely possible to make a living out of photography, but if the motivation is driving purely monetary gain in the beginning, it is going to be hard work, not impossible.
However, nothing beats the proper planning like what Kentwong81 has mentioned.
The funny thing about marketing is this... people are looking for ways to market their service... BUT... 1. They don't know who to market it to and 2. They don't know if they have a "Product" that they like to "sell".
Sorry to say this, but you can't sell AIR... since it is given to us FREE from GOD. however, you can sell "Purifier" to take away those "Junk" inside the air.
So just think about it... What do you have and who do you target, if you can identify the minimum of these 2, ask yourself, does your target market want what you are selling?
Stop DREAMING and do something... Even if you know "IT", you still can't be successful without doing "IT". "IT" I refer to business knowledge.
Work Hard, work smart and you shall be rewarded with "Luck". But don't depend on it.
