Help with a unicycle video

Hey guys,

Just a quick request to see if anyone can help me.
I am hoping to do a cross country ride from coast to coast (UK) in August and will need either a 29" or 36" unicycle.
Unfortunately I am not flush with money so am applying for a grant through work to get me a unicycle. As part of the application I have chosen to make a short video about what I am planning to do and what new equipment I am going to need.

Here is where you come in. What I need is some film of people unicycling.
Specifically I would like someone riding a 36" next to a 29" and 20" to demonstrate speed and size differences.
I could also do with a few stills of a 20" next to both a 29" and 36".

Any help would be greatly appreciated and the film will be uploaded to youtube for your viewing pleasures!

Thanks
Andy

BUMP

Is anyone able to point me in the right direction. I really do need some footage of different sized unicycles and comparisons of speed if possible!
