deep etching photographs

I need someone to deep etch some jewellery images and put them onto a slate grey background. The images are to be used on a website. There are approximately 45 to 50 images to be deep etched. I have attached a sample of the images for you to look at. Of course, I would like this to be a quality job where all of the colours in the piece of jewellery remain intact and the edges of the jewellery are properly formed. In addition, I have one image which is quite faint and it needs the colour to be enhanced. Could you please quote on this and let me know roughly how long it would take you once I sent the images.
