Startled birds animation library

[tricky]

I'd like to find an off-the-shelf animation of birds pecking around on the ground and then taking off as a flock - as though a child has run over to them and startled them. I am doubtful this exists, and my animation skills are minimal. It needs to work from mid distance only - I'm not going to get closer than around 5m from them. Does anyone know if such a thing exists to purchase, or would anyone be up for the task of creating this for me to work in Max2009 x64 with Vray textures? I'd be interested to know how much you would charge and how long it might take.

This kind of thing really (though a few more pigeons in a group) http://www.youtube.com/watch?v=QcUrNx9MRM8
