Need Pro video maker for "How to use...(electronic gadget)" guide

We would like to make video user guide for our electronic gadgets, such as Bluetooth stereo headset, Bluetooth audio adapter, Bluetooth car kits, etc.

The video can be in this style -
https://www.youtube.com/watch?v=L49gSh4rRh4

or - http://www.youtube.com/watch?v=L7IMzOjDXog

Or in this style - http://www.youtube.com/watch?v=exYq2XYzhMs

The content is like this (from 60s to end) - https://www.youtube.com/watch?v=MPxMzhqqaMc

We do not need animation. We need real life talk / video with or without face show. Voice over will be great, but not a must.

We prefer the picture to be stylish, modern, clean, simple... fit Avantree (our brand) style.

We are based in HK. But the job can be done anywhere in the world. We will provide the product, maybe scrip and our ideas (if needed) to you.

This is a first project of many. We are looking for long term partners.

Thanks

Phoebe
