I need British wildlife photos and images

Hello - We are a UK-based label printing company. We sell stickers on a variety of themes through eBay and Amazon, many of these sticker packs are low-value but we sell in high volume. We would like to introduce a range of photographic British wildlife stickers - We're looking to obtain images which we could then print onto our labels. An individual who already had access to such images would probably be preferable for us that we could then purchase as a set. We're quite open as to the type of wildlife - Birds, butterflies, foxes, deer, badgers, hedgehogs. We'd need to be able to fit the images onto fairly small circular, or rectangular labels (minimum 25mm round but could be larger).
