I need 3 short animation sequences for one promo video

I need an animated graphics section to fit into a 60 sec video I'm doing for an existing client. I do all his work, but for this latest job he needs animated graphics which I cannot do myself. I've told my client I cannot do the graphics but he is happy for me to handle it using a third party to do the animation for me.

This sequence will be the middle section I need someone to do for me. I will top and tail the video.

Let me explain the job through the words of my client to see if you're interested ...

BRIEF STARTS:-

The required sequence is based on a house interior, just one room where we see animated arrows showing how the heat travels within the room.

I need something based on this sample ... http://www.youtube.com/watch?v=IcQaNDfRGlg

I need somethingsimilar to the convection diagram at 54 secs, bouncing balls at 1.25 and would need 1 more showing heat radiating back. Don't need a 3D.



Will need to show a house interior with ...

1 – Animation sequence of convection heating which circulates around the room – moving arrow to go round

2 – The “bouncing ball” animation sequence showing a panel on the roof or wall with arrows coming off and bouncing off the walls etc

3 – Animation sequence showing arrows coming back from furniture, floor, ceiling etc


So, could you let me know ...

1. If you can do it as per sample?
2. When you could have it completed by?
3. How much you would charge me?

Many thanks.
