A friend and I are talking about taking our hobby of printing funny T-shirts into a living, and start our own website in Sydney. And then we need to find a cheap marketing company who can provide support and have experiences in helping start-up companies. Anyone who knows a marketing company in Sydney, matching that description?

I would strongly suggest beginning by using Cafepress or even something like Etsy to sell your custom T-shirt designs. Lots of upside, they take care of getting you up and going quick, and you retain the ownership of your designs. With Etsy you’re creating the complete product by yourself so you’re in complete control of quality. Once you have a following, then you can take on all the hidden costs of doing everything yourself.
