Starting with FB page is always easier to get you going , Wix meant to do nice and easy to make websites. Also did you consider using google ads ? I think they give you something like £120 credits when you first start ( it’s where your website appears as ‘sponsored’ on top of the search in the area you set , and yo pay for click. It’s quite a small investment and bound to get you started especially if you are willing to fulfil last minute orders. All the admin is a huge time commitment , but none is impossible, especially this day and age so don’t be scared of it if you are determined, good luck
