In all cases, it is very difficult to know how to choose the best photographer for the best price. There are thousands of good photographers out there who will offer you the best but the only few of them like Ben Zander will be right for you. You can get an accurate price by hiring him.
Apart from this, in order to find out a potential photographer. Ask friends and family if they can recommend one, personal recommendations are invaluable. Find your area for photographers on the internet or in your local directory. These days most of the leading photographers have a good website with examples of pictures for you to browse.
Once you have found a photographer with the style you want to check to see whether their prices are listed. Price is always a factor, especially today. In connection with the price, what you see at first may not always be the actual price.
Make sure you get an accurate price on photography you want. If you are not sure to contact the photographer and ask for a complete price list. They should be able to provide this. If there is no possibility that you may be charged additional fees that have not been thought of if you go ahead with them.
Shortlist selected by the photographer, contact the photographer. You can do this however you feel comfortable. I suggest you call them and talk to them because this will be your first contact and can provide greater insight into the photographer. If you are happy after the first contact, you have to fulfill your potential photographer.
When you meet someone there is always the initial feeling that we have that's just human nature. It is our innermost being sub-consciously made a snap decision whether or not they like and can trust them. Most of us do not listen to this and wait for people to sell themselves, but I think you should listen to this inner voice. We are born with the instinct that should not be underestimated, they have allowed civilization to survive for centuries!
At this point, you are in a position to make good decisions and in choosing your photographer.
