Have you considered one of those online shopping proxies? They let you upload your brand logo(s) and then anybody can buy all manner of objects with your logo printed on (yes, even thongs, Monocock!) They transfer your profit to you once a month or something like that. Lots of sites I frequent seem to have a link to a shop done that way. badscience.net, for example, uses
www.spreadshirt.co.uk but there are loads of others. Might be less hassle to organise in future? Just my 2p worth.
