A typographic/infographic promotional video for my business

I would like to create a 60-90 second promotional video for a business (I will potentially be look for 2 more videos once this one is created). I want it to explain what the business is, who we sell to and why you should use us. I will provide the script. I want it to look bright and modern with the use of lots of graphics to explain what we do and bring it to life a bit. Please quote a price excluding a voice over and let me know how much extra you charge to include a voiceover with the video.

Please send me a link to some of your existing work when bidding.

Thanks
