Hello,
Photoshop have the features to transform any vertical object to horizontal. Rotate, Skew, Distort, Perspective, Warp, Scale and free transform are the lists of image altering/modifying tools from Photoshop. So with one or more of these tools, I can professionally change your 3 vertical photos to horizontal view. You'll get quick and quality turnaround.
Finally I'm looking forward to work with you.
Regards,
Mahmudar
