Free of cost? You mean even printing costs :D

Yes including printing costs, I just saw you are in Australia however, delivery may be difficult, but there is nothing stopping someone starting the #promo-australia and using this same model. We can provide you with all our designs for flyers , tshirts, pens, mugs, caps and promote the fact you are going to promote steemit in australia on our blogs.
The way we raise funds is to announce that we are going to get flyers printed on steemit, then we will blog to announce our plans to flyer and finally we blog the actual flyering itself. The up votes from the wonderful people on this thread normally cover the flyer costs, travel, T-shirts etc. if you are interested, and would like to contact our team to further discuss I can arrange a quick chat over the phone
