If I may suggest (in no particular order):
1) Define yourself in your marketplace.
Exactly who is your customer? If you answer, "Anyone who has money," then you lose.
What does your business do? If you answer, "Take pictures," then you lose.
What is your focus? If you say, "Auto," that's only a little bit funny
Understand that everyone is not your customer. That's a good thing. If you try to be everything to everyone, you risk being nothing to anyone. Remember
Putney Swope saying, "I can get anybody for nothing."
2) Why should a customer spend their money on you and not the other photographer? If you answer "Because I'm a better photographer," then you lose.
3) If you think you can discount your way to success, then you lose. It isn't mathematically possible.
4) The purpose of running a business is to make money. Learn to talk money.
5) Your portfolio (web site) should show both where you've been, photographically speaking, and where you'd like to go. Show what you want to shoot. This may sound simple but many photographers don't know what they want to shoot.
"Would you tell me, please, which way I ought to go from here?" asked Alice.
"That depends a good deal on where you want to get to," said the Cheshire Cat.
"I don't much care where..." said Alice.
"Then it doesn't matter which way you go," said the Cat.
"...so long as I get somewhere," Alice added as an explanation.
"Oh, you're sure to do that," said the Cat, "if you only walk long enough."
6) You're worth what the customer thinks you're worth. But your marketing goal is to influence their opinion of you. Your marketing is more important than your photography.
7) Wear nice shoes once in a while. And read a book or two.
