Simple website design (wix or similar) for local brownie co

Description

We are looking for a basic website where people are able to place pre orders on stock we make available once a week.
We will be selling brownies in boxes of three, six and nine and want to be able to pre load the stock of each brownie type (there will be multipleFlavours) so that as people place orders, the stock levels will drop until we go out of stock.
We have the logos etc to use and the website should match the branding
There will also need to be a check out function for people to purchase
