Tresta, what you can price your services/photos at depends on what people value them at.

You need to figure in a lot more than camera costs. TIME costs. The most important thing is to not start charging people without being able to deliver a consistent quality product. Going into business too soon will do nothing but harm you in the long run.

I have a money back guarantee. I have never had anyone ask for their money back, but, I have done reshoots. One was due to factors under my control, another was due to factors not under my control. Doesn't matter, I reshoot if people are not thrilled with their photos

I shot for free for a long time until I was sure I could give people a consistent product. I shot A LOT during that time too.
