Alter some Images

Hello, Im after a photoshop expert for a very simple job for someone who knows what they are doing. I have 3 images 1 picture of a local landscape 2 picture of man in speedos 3 picture of robot off lmfao all im needing is first i want the robot head put on the man with the speedos and cut image out so has a transparent background. and the speedos i want changed to a pink colour and appropriate shadows etc to look real. 2nd simply place image into front of landscape image also with making shadows and sofening to look like a real shot. This should be quick for somone who uses photoshop reguarly and i also need back today so please only bid if you have the experience and are free to produce today> Thanks Andy ps alot of ongoing work for the right person for a magazine im launching
