To answer your questions regarding my clients- I did a few free shoots last year to build a portfolio once I felt comfortbale I started charging for my time, and built in the cost of products I would need to purchase (IE newborn shoot, I had limited props and purchased more, I built that into my cost). With my very first newborn, I told my client flat out, I had never done a newborn before, but had met with a local friend who did newborn photography and shadowed a few times. She was comfortable with that and we proceeded. In terms of other shoots, while I did advertise, most of my clients came from word of mouth. I have had a few clients order pictures, even though I do give the edited digitals and print release. I did have 1 out of my 30 clients disappointed in their photos- however they were aware of limited experience, and must not have been too upset as they ended up using my photos for both their Facebook cover photo and profile picture. I hope that clears up any questions you all may have.
So in summery, I don't consider myself a pro, how could I? I have been taking this seriously for 7 months and have a lot to learn-at the same time, regardless of if my photos are fantastic or not, my time, gas, and time editing the photos is worth something.
