Hi,
I have a good experience in Video Services and Video Editing, etc... But I doesn't have lot of reviews in freelancer for these relevant skills. But I confirm you I can merge 27 videos in to one video with design works very well. I can provide sample video for the clarification about my work. Also if you want to negotiate budget and days I agree with it. Please contact me for more details.
Regards,
