I don't think the suggestion was that the OP launch a car dealership or start a cell phone manufacturing venture. I think the suggestion was, essentially, "If you need money quickly, get a job that pays a wage" which is extremely sound advice.
Okay, so there's basically three categories of jobs relevant to this thread:
1) Unskilled wage labor that pays minimum wage and doesn't require a resume other than not being a sex offending guy with no limbs. This is what the OP needs to get now if he needs to pay next month's rent.
2) Skilled labor in areas other than photography, which will require a resume and skills and will take some years to build up to. For instance, working at a car dealership in sales. Or starting your own bakery.
3) Skilled labor in photography, which will also require a resume and skills that will take some years to build up to. Whether it be with an existing company (newspapers for example) or starting your own business.
So we all agree that #1 is what he needs now if he is desperate for cash and doesn't know what he is doing.
My point, though, is that while he is working at a job in category #1, he might as well be training and getting the skills in his free time for a job in category #3, if photography is what makes him happiest. Because it won't be any more effort than getting a good job in category #2 later on.
