I have been working with Adobe Photoshop for the last twenty years and feel confident about the working with your images. As with all work you have to be careful as not all images can be rescued if they have been shot under bad conditions.
I prefer retouching an image in a natural way. That means if I do my job well you don't even see that I've actually manipulated the image in any way. I'm currently building up my account here as a second income, so my current rate is below what I usually take :)
