If you are looking for a Shopify developer in Perth, the chances are you do not need a brand new store. You have one already, and it is fighting you. A section cannot be changed without breaking another page, an app has been bolted on and now every page loads slower, and the collection filters do not work on a phone.
Shopify themes are written in Liquid, Shopify's own templating language. If you can write it, you can change almost anything about how a store renders, and you can do it inside the theme rather than on top of it.
There is no price list for theme work, because the same brief can be a week or two months depending on how much of your current theme survives.
What we look at first, in the order it usually matters:
Then you get a fixed price for a defined scope, in writing, and a plain list of what sits outside it.

We are a founder-led agency in Perth, Western Australia.
We are the ones doing the work. Nothing is passed to a junior or offshored, which is also why we are careful about how much we take on.
If you want a starting point, send us the store URL and tell us what is annoying you about it. We will look at the theme and tell you whether it needs fixing, extending or replacing, and we will say so even when the answer is smaller than you expected.
Send us your store URL and what you want fixed, whether that is a new build, a theme rebuild or a migration off another platform. We will come back with specifics, not a generic pitch. If you would rather talk it through, call us.
