Highly Creative Flash Intro Needed

I need a flash intro created for a website I am developing. The intro should be 7 to 10 seconds, it needs to be very creative. Its for a company that designs and manufactures custom toys / holiday decorations. We have the concept of what we want, but would need to have it built. You would need to be creative to "fill in the blanks" from our general idea of what this should look like. The client is very picky so you MUST be OK with making changes (and factoring that into the price) until we get exactly what we want (I will do my part to keep this to as much of a minimum as possible). We would do a "rough draft" that is a quick mockup to present to them, then based on their feedback do a final version (that would probably have a round or two of revisions itself). We have the website pretty much built so you can look to that for the style / colors - we have the images to use for the intro but you would have to do some more illustrations in flash. The concept is to show a product (a toy train) being built from start to finish - from the first idea, to the sketch, the design, the buiding and the kid receiving the train... as the train moves across the screen. I will provide more details, including photos of the actual train to use, upon product selection. Only if you feel qualified to do all of the above please provide: 1.) examples of 2 best flash intros you have done (only 2) with custom illustration 2.) How long it would take to come up with the first draft / final copy once I get you all info / the OK from the client. 3.) Total cost. Payment is via ESCROW ONLY
