May I introduce Illumination Productions as your potential video production company for the production you have listed on Freelancer.com.
After viewing the video you have posted as an example, my skillset is particularly in line with your project due to my experience filming with schools and with children. Over the past number of years, I have worked with a Brisbane production company filming in schools for the QCAA, Deet and Griffith University. Working on separate projects for these organisations I have travelled the length and breadth of Queensland to film in schools of all age groups. I understand the sector and have the ability to sensitively shoot around children of all ages.
It is not only my skills that are in line with your project; the equipment I use is also. The example video utilises a moving camera for the majority of the overlay and to fulfil this element in your project, my DJI Ronin is at your disposal. The Ronin carries the camera on a 3-axis gimbal and affords rock steady movement to the shot, much like a Steadicam but at a fraction of the cost.
One concern with the example video I have is that it is very long and is not particularly punchy. I still am yet to get a full grasp of what it is you require, but an immediate improvement on the example provided that I can guarantee is that anything I produce for you will be far more engaging for the viewer.
