Make a Video

I have a product which is fit for kids & professional. We want to start marketing for this product, so want to do a real life video with the real use cases. The video should be shot with kids/family usage, professionals etc and should be able to show the real usage of product, so we can relate it with day to day usage & promote in marketing & sales. I am not sure how it will be done. So, only people who have experience with such product/job and can give me enough details here, pls apply for project. I can share the product details etc once we get some details. Videos etc can be done anywhere in world, where we can find cost effective resources. Detailing will be important for us & quality of work as it can be promoted everywhere online.
