You have heard of YouTube?

Can she create videos of employees working for local businesses?

Eg. A roofing contractor shows a video of their crew at work, a paving contractor shows how they repair cracks etc. etc.

These can be stored on YouTube and displayed on their own websites without using up expensive bandwidth - use YouTube's bandwidth for free!

Nothing conveys trust more than having the owner of a business tell you in video how they work and show themselves working.

Without YouTube they would have to get a dedicated server/VPS with huge bandwidth allowances but now this is possible for anyone.
