Help Start Photography Business

My Name is Sean Radley, I am a US Army Disabled Veteran and have been out of work for sometime due to injuries to my knee, I am now in the process of getting back on my feet and trying to start my photography business. I have done quite a bit of freelance work but now would like to start a business doing what i love. Getting extra money is very hard as i am a father of 3 beautiful kids and most of my money goes to my kids so buying equipment and supplies is very hard , i would like to start as  soon as i can but am patient .  Getting my life back in order and being able to benefit from doing something i love would be a dream come true. Accomplishing this goal in my life would be amazing and i would be very grateful of any help that is given.
