Create 3+ perfectly seamless panoramic images (photo stitching)

To begin with, I need 3 perfectly seamless panoramic (horizontal) images created (aka photo stitching). The first one has 21 photographs, and the second and third each have 7 photos. There's 25% to 50% overlap between the images. All photos are approximately 21 megapixels. See attached ZIP files for the actual photos to be merged.

PLEASE NOTE: I will need more panoramic images stitched together in the near future, so additional milestones will need to be added (and you will be paid appropriately). I really need one "go to person" who can do this sort of task on a regular basis and will not disappear after the first job.

I've already tried this using the Photoshop CS6 photomerge feature but it was not able to automatically stitch them together correctly.

Thank you!

UPDATE: I am unable to attach the images to be stitched because they are too big to upload to Freelancer. The total size is 484 MB for the 3 panoramas (35 photos total to merge).
