Ok I'm coming to you guys after a week or reading and not really knowing what on earth to do. I'm hoping maybe someone here can offer some direction!

So I've been shooting for a while now. I shoot a lot of different areas. I havn't yet been pigeon-holed into one particular genre of photography. I really enjoy it all to be honest. When someone comes to me with a job, I take it. Although it's not very often. I still mostly shoot for free, and for FUN...
Recently I was laid off my job, and I've decided that while I'm living off unemployment, I should probably take this time to get my photo biz off the ground, so that I don't EVER have to go back to cubicle land.
I feel like I have the talent to make this happen... but the business side, I'm TOTALLY lost.
I know that I need to create a business plan. But how?
And can I do that without spending MONEY?
I keep seeing things online about buying the paperwork etc for a business plan....is that the best way? Do you guys have any ideas?
Also - I've been reading about the differeneces and benefits between getting LLC'd...or just getting a tax ID and registering my business name.
Can anyone offer any insight as to what they did, and what they prefer??
and here's my big question...
MARKETING.
I've GOT to bring in business, obviously, if I'm going to make this a business. Most of my clients come to me from word of mouth. Which is fantastic...but I need new clients, and consistency!!
Any help would be fantastic guys!!!
Thank you so much!!
Sincerely,
A Wannabe Professional Photographer
