Personally, I'm involved in producing an animated FLASH Webisode at the moment that is costing approximately AUD$6,500.00 to produce the first 1-minute pilot. The client hopes to get this to around $2,000.00 per minute eventually, but I think $3,000.00 is more realistic.
Why? Because a Flash Animator (who is, after all, a specialist) worth his or her salt will be able to, depending on complexity, produce 30 seconds of Flash animation in a week and will usually charge about AUD$1,200.00 for the effort. Factor in GST, and you have a bill of $2,640.00 for a minute of Flash animation.
Of course, how much you can do in a week is largely up to how picky the client is and how many notes they throw at you.
