Photoshop professional needed

help of a capable photoshop freelancer is needed -

I wanted to place three photos of kids in line (stitiching them together to produce a side scrollable photo). I will deliver the photos. the photos are Black and White and taken in the same ambient light.
the final photo should be displayed in a website later as a background photo, so some redundant deltails should be eliminated, brighness and contrast must be harmonized.

Please give me a quote if this could be your job!
