Also think this is a fantastic opportunity for people, especially younger riders, as there is so much talent out there at the moment that goes unrecognised and supported. I'd be happy just riding under the 'Tarty Bikes' name, let alone discount on parts. Its a nice idea to get people to 'apply' for sponsorship.
A few t-shirts and cheap parts go along way for just having a good attitude and enjoying your sport / hobby.
I think it would be a good idea, for those less technically abled on the video side (which isn't that many people, as Im sure they can get on movie maker and put together something standard), for you to maybe offer a little help putting a video together, as you would both reap the benefits.
Also I would love to see a Tarty Bikes Team Video, to showcase all of your riders, I would even go as far as paying a bit of dollar for it if the production was good quality, as I'm sure it would be. It would greatly promote the company, the riders and also the sport. Just think how many BMX / Skate team videos there are and how they help the sport and companies.
