Short animated video for my business website

I'd like a short animated video for my website. The type of video I am keen on is where the video tells a story almost, little graphics with hands moving the images in and out of frame with a voiceover. However, if you feel another type of video would be more suitable, modern, relevant I'm all ears.

My business is a technology lending service and I feel a video would portray a scenario for my market better than text.

Here are some examples of the types of videos I'm talking about;

I have no idea how much something like this should cost so I am looking to you to make reasonable offers.

Thank you
