Attention : Animated Video Creator

Are you an expert Animated Video Creator with an experience of more than 3 years. I'm setting up a new website up for an e-commerce brand I'm launching, I'm currently looking for a 30 to 60 seconds animated video for our website with the same level of quality as this: [login to view URL] with script, voice-over, storyboard, and animation included and revisions as well. It would be really helpful if you provide with a few examples for your work and the estimated cost for the given level of quality. I'm speaking to a range of vendors and once I know the expected budget I'll be able to take the conversation forward. Also are there additional costs such as extra revisions I should be aware of? Please let me know that you’ve read and understood this job post, please start off your response with how many years you’ve been doing this for. Thanks
