I think I speak for myself as well as a lot of other photographers. As far as going from no clients to charging standard rates is done by doing the following.
This is what I did, of course this was in 1980 when I started as a professional "fashion" photographer.
Shoot lots of friends, family, friends of friends of family, etc. for FREE!!! LEARN WHAT YOU ARE DOING! Get a good portfolio to show clients that are willing to pay, then put together packages at current rates.
Now before anyone flames me I feel NO ONE should pick up a camera and start charging for photography until they know what they are doing. Look at it as school and you are paying tuition. I know in the digital age "everyone" is a photographer because everyone can afford a good camera, and has a photo printer.
People tend to respect a photographer if you are still learning and are upfront with shooting them for a learning experience to build a portfolio. If they want to pay you, let them offer what they want, don't expect anything.
When you have great samples, that you can show people, not just 2 to 3 people, at least 10, then you can justify charging a price that is fair for both parties.
My career was not really so much portrait related. I shot models, actors and entertainers. I probably shot 5% of the people I shot for free my entire career(1980-2007), because they were great for my portfolio and made my paying clients want me that much more.
I think now adays, people want to make the good money instantly. When I approached the Agencies I eventually worked with full time, I had 10 "average to good shots", was honest with them and told them I was going to shoot for a living and be around for the long haul. I asked them to supply my with models to shoot for TFP. I shot for 3 months straight, not making as dime. But, my portfolio was top notch after 3 months. And according to my business plan, I closed the "free" door and never looked back. I started charging the same thing as the other guys were charging, stuck by my guns and did very well.
Did I ever discount? I ran specials for a few times, and found I shot fewer people and made less money. I had a REASONABLE fee, and I stuck with it. Fow over 10 years I was booked over 30 days in advance, shooting 3-8 sessions a day 5 days a week, at regular rate. I always gave a discount to repeat customers, because I appreciated them returning.
I guess my point is most of us that shoot for a living hate to see anyone doing photography and trying to charge for something when they have no clue what they are doing (not meant to any posts in this thread).
Learn what you are doing, charge accordingly, MARKET CORRECTLY, and you should have no problem making money.
I have a friend who is now shooting that I help "manage". He is doing very well, and is a average shooter. However, we do a great deal or marketing and ALWAYS make the client think he is almost too busy to shoot them. You have to make them "want" you. If you slash your prices and haggle, that shows desperation, people sense that.
Just like in any other business, it is extremely easy to make money. Treat your customers fair, charge a fair price, and give everyone 110% and you will always have customers.
just my 2 cents
