Isn't this your best means to get sponsored though??? More of a local guy?? If it is just someone over the web wouldn't they want to meet you and see your personality etc to see if you the type of guy they want to sponsor. Making the sponsor incur more costs by meeting you and actually seeing you ride or train.
As a 5 second - 5 minute video can't tell the whole story.
Again not my thing, just wondering.
