If NORE's downthumbs suggestion became reality none of your posts would be visible to the Forvm, and I wouldn't even have to read your posts when they are quoted by other people. Start giving advice to people when you start demonstrating a basic understanding of how to dress coherently and confidently.
EDIT: Also, as enthusiastic as you are about your product, I find your website confusing to navigate and there isn't much too information regarding where the fabrics are milled, excluding the Taylor & Lodge category.
Try posting in the Australian Members thread for some more answers, but the prices you mentioned seem pretty reasonable for Aus. If you want to ensure all of the work is being done well, save the extra cash and take it to a bespoke tailor. You can find a list of bespoke tailors in Sydney here.
