How to start my own business?

If I wanted to start a photography business. Where should I start? By the way, I do not have much money. I was thinking putting ads on criglist and starting from there. T
I have a Nikon D3100 14.2MP Digital SLR Camera and no studio. I was thinking people could pay me to take photos of parties or other events for a low price. Then build from there. Save some money get more equipment.

Is this possible?

Yes but it's a long, long road. I recommend starting by volunteering to do free gigs. Perhaps there's someone already established you can apprentice under…

I have a few friends who started out by taking pictures for friends on a part time basis in natural settings. What you need is another source of income that can help you get the funds that you need to build your studio. I know someone who can help you if your interested.
