As a professional photographer, it would be in my interest to advise you to have professional photographs of yourself. Personally, it is a mistake not to have one! It is very easy to point a camera and take a photo of someone, but that's just not good enough for an image that may be seen by millions!
I am happy to advise as to the style, location, clothing; In fact, I will offer advice in any area if it will provide you with a better image. In these days of the internet and social media your face is out there. A bad photograph could seen by millions, a good image will be remembered by millions.
Over the years I have provided corporate portraits for many businesses and personalities. Many of these images still appear now!
