Flat rate shipping per each item

Hey guys,
how are you all doing?
I’m dealing with an issue I need to solve asap.
I’m setting up a restaurant page for my client. The problem is – he needs to accept orders week in advance.
Example: Customer can order food for a whole week. The order is sent by this customer on monday (order includes food for monday, tuesday, wednesday etc…). My client then delivers food each single day to the customer.
I need to make a shipping formula =>
If it’s only 1 food for f.e. monday – apply standard fee – 5$
If it’s 2 and more foods for f.e. monday – apply same fee – 5$

The problem is – imagine I have different menu for each day during a week. I need Woocommerce to somehow recognize, that:
If it’s 2 and more foods for f.e. monday – apply fee – 5$
If it’s 2 and more foods for f.e. wednesday- apply same fee – 5$

If it’s 2 and more foods for whole week – 5 days- 5$ * 5$ = 25$ in total

Also I need to change shipping fee according to customer’s ZIP Code.

Can anyone help me with this problem?

Thank you!
