Converting Photos to B/W Coloring Pages (images) for murals

I need a photo editor/ graphic designer to create black and white "coloring page" for 10 murals for events I am doing. I am attaching an image to show the end mural product. The file just needs to be high resolution vector file. If I give you photos and basic design layout, you create the B/W coloring page vector file. Need price per hour, what kind of turnaround time, how much you estimate each mural design will take (took me, myself two hours to create one of these). The 10 mural images are needed over a two month period, May and June basically, may start sooner... Would you send me a sample of what you have done like this?
