Animated Video for New Website

I have recently launched a new website and need a short animated video that will clearly explain the website and business concept to new users. This must be a professional video that aligns with the site and current brand. I am hoping to explain the website to the person that I work with so that they can then use their expertise to create the video. An Australian voice over would be good but a voice over is not essential if the message is clear without the use of voice. The website is currently live ([login to view URL]) and I can share the logo, the icon set and any images that you require. The end product should be uploaded to a specified dropbox folder so that I can upload it to my site and to social platforms. Please message me with any questions that you have in relation to this that will help you provide an accurate quote.
