Set up shipping on my website www.foundgarden.com.au

I create succulent gardens and want to set up shipping options on my website. I have tried to create Shipping Zones in WooCommerce but it's not proving to be a simple process and was hoping someone could sort it out for me.. Basically I only want to deliver within Australia and there are 3 shipping zones and prices: Local Pickup from Avoca Beach (NSW Central Coast) : FREE Courier (NSW Central Coast) : $10 (I entered specific postcodes unique to this area) Courier (rest of Australia) : $15 Can someone help set up these charges on the checkout? How much will you charge to do this work? There may be opportunity to do further work later but my budget is very limited at the moment. Thanks, Virginia PS I'm hoping to get this fixed urgently as I want to try and sell some gardens for Valentines day Feb 14.
