I need a 30-45 second video for my new website

We are an Apple hiring company launching soon, we hire out mainly tablets with a point of sale system to be used at events for sales etc..

We need a video for the homepage of our website showing what we do.

This video needs to be a cartoon and be made to have a voiceover attached at a later date, the video should show someone hiring an iPad from us and using the point of sales system to complete a transaction.

Please reply to this with ideas of the video, I am open to discussion and look forward to coming up with ideas with potential candidates.
