I've been asked by a major computer manufacturer to provide a licensing quote for them to use one of my images for desktop/screensaver use. The image will be embedded in their products and sold pre-installed in the software - worldwide for 5 year duration. Fotoquote suggests $1600-$2400 per 50-100K copies - which is what I initially provided to them.
Given the significantly larger volume of copies they sell they prefer "Unlimited Usage Worldwide" but still in the $1600-$2400 price range as a one time payment.
As I've never licensed for screensavers at a corporate level such as this - is this a reasonable price for this type of license? If not, what would be appropriate?
