Custom Online Shopping Cart for Donut Shop

Ok this add is probably looking for a ninja developer to make this work...

I own a donut shop here in Oregon and since Covid-19 we have been limited to only deliveries and pick up orders. Our entire business model has had to adapt almost overnight and I have to get a better system for online orders. Currently we are just writing down messages from facebook messenger and its making me go insane lol.

Food Groups (Like appetizers) >Items (Like a salad) > Modifiers (Like no onions, extra tomatoes etc...)
however, since our business allows for EACH donut to be customized it adds another layer in the ordering process.
Food Groups (Donuts) >Items (Custom Dozen) >Modifiers (Donut 1) > Glaze Options (Maple, Chocolate, Vanilla) > Toppings (Oreos, Cream Cheese, Sprinkles etc...) ................. Then Donut 2 and 3 all the way to a ---------- s almost like allowing someone to customize each slice of a pizza if that makes sense.

So I need someone who can make this functionally happen, easy to use for a customer, looks awesome, and can work with Square for merchant processing.

Our business is called Mac Daddy Donuts & you can learn and see a little of what we ----------
