I need an introductiory/explainatory video for a new online platform

Hi

I would like an introductory/explainatory video created for my online platform.

I was looking through your portfolio and enjoy the 'Flat icon style explainer style' and the Pro explainer style video
I am thinking of using the same style for my video for an online sticky notes platform, with the purpose of briefly explaining what we do, how it can improve people's lives (ie help them), and to market our product as being simple, easy to use and collaborative.

Can you give me a quote for this video for 90seconds (and 60 seconds)? with and without voiceover.

can you also give me an idea of the turnaround time for this.

thanks
Jack
