Hi There,
I am a web developer with more than 5 years experience in developing ecommerce websites. I will create the interface for your website first and when you approved it I would start the next step. My design will be responsive, so in addition to Desktop, you will see it great on Mobile phones and tablets. It also help, your web site pass google tests and find a better rank in Search Engines. For back-end development I will use ASP.NET and MVC which is the latest technology of Microsoft. For front end I will use HTML5, CSS3, javascript and AngularJS. and our database will be SQL Server. Please note that the website you mentioned is not responsive , so Our design would looks even better. I also live in Sydney and we can have a meeting if needed.
