526311 Photoshop edits/tweaks on existing images

Hi we have 3 images which need adjusting and the colours changing on them. 1. An existing logo, which needs colours brighting up, maybe changing? 2. A a6 booklet front cover which needs the logo placing on the front and back 3. 2 round stickers which need a 3mm bleed in separate files to send to printers. This is a really quick job for a photoshop/designer. I have lots of other outstanding design work to be given as further large projects and this will be a good taster job to see how we get on and how quick/good you are. Thanks Ash
