Ask HN: Creating screencast to raise funds?

Hi. I am trying to launch a startup but I have no coding skills so I decided I would hire someone to code it for me, but to do that I need money. The only skill I have is creating videos, and so I am thinking that creating screencasts and intro videos for startups would be a good way to go. I am looking for advice on how to get screencasting gigs, and how much I might charge for them. For example, say I can create the intro video on dropbox.com, how much should I be charging for that? Any advice would be appreciated. Thanks.
