Mural of me protecting my wife and child from a Animal

I want to make a mural of me fighting off a big animal like tiger or something and behind me my wife and child. See the attachment of a picture I saw online of president clinton, I am thinking of something like that picture. I am thinking of me wearing the military uniform, having my long fake hair and nice mustache. I want to make the mural to be able to print on a paper around 4ft by 5ft, so if you can draw it on photoshop or any other digital software it will be nice and I can go get it printed. Please send me E-mail of what you think and how much time you think you will need. And if you can say well I can make it with certain detail for $xx, but with more detail $yy then please do so I have a better idea of what you are capable of. Thank You in Advance, William Jerez
