I have met a few Genealogist and Historians during my course of work and many times they come to me and show me pictures of black and white or sepia photographs that they have managed to have had colourized.
I can tell you that the people that do these are pretty amazing; I have managed to secure the services of one such person, who will, for a small fee colour black and white or sepia pictures for you.
In an effort to show you the brilliance of the picture change, I have had a couple of pictures done.
I also believe that the fees that this person charges are very reasonable indeed, the cost is on an application basis, but to simplify it for you, I have been told that it is between £3.00 to £7.00 depending on the size and complexity of the picture. So why don't you give him a try, by contacting me using the contact form . Please let us know things like the persons hair colour and skin tones to make the picture more authentic.
Below is a couple of examples of his work.
