Whiteboard animation

Design details: Hello, I am looking to buy a short animation that presents my new business to be hosted on a webpage. I have a good idea on the content/script but am looking for some extra help and hopefully further improve upon my ideas. The introduction is basically text with the animation of my logo and then the service is to be demonstrated by a swiss army style tool with approx. 14 tools that need to be extended individually and have associated bubble/text to explain and finally all tools working together.

At this stage I have no idea of what the likely budget is or should be as existing sellers are between £12 and £500, on which basis I am happy to spend c200-300 for the right job.

I am happy to receive proposals or links to anything similar/comparable.

Will need music, and ability to link to social media if possible.

Thanks in anticipation..
Ideas for the visual style: handrawn
