Advertising Sponsor Required

I'm looking for some sponsors for a shirt I want to get made up. I'm looking for 3 sponsors to provide money for the shirt and Help for Heroes in return for their logo on the kit. I'm offering 1 large chest or back logo for offers of £300 upwards and 2 sponsors of £100 upwards for an arm and leg logo. These prices are based upon a kit for myself but I may have another rider joining in so I would be asking for £600 and £200 to cover the additional costs and ensuring that the charity gets a decent amount.

This is a mock up of the shirt to give people an idea of how it might look. If you have a business of know of someone who would be interested please point them in my direction.
