Build video animation for campaigns

Hey, We are in the information-gathering stage for animated video business, so we are reaching out to a few companies in the space, I am setting up a new website up for an e-commerce brand I am launching, I'm currently looking for: a 60 second 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. Please give me an estimated cost based on that and let me know if you need any more information to provide a quote, I am speaking to a range of vendors and once I know the expected budget, we will be able to take the conversation forward. Also are their additional costs such as extra revisions I should be aware of? my boss liked the most if you could provide insights on these questions, it would really help our decision-making process: 1. What is the typical production process you go through for this type of project? 2. Is there anything I should be aware of in terms of common issues when working on video animated projects? 3. Are there any extras you recommend I include in video animated project to improve the final deliverable? 4. What is the typical use case you deal with? Have you worked with companies like ours before? Cheers,
