Hi,
I'm in need of a custom app for my shopify store that allows me to make my local delivery option exactly what I need. In short I've tried the existing shopify apps, and I can't get exactly what I want out of them.
What I need:
Control local delivery options with shipping zones set by zip code (exact match)
Offering one hour delivery, and selectable two hour delivery windows
Limit number of deliveries per shipping window
One hour delivery shipping option only offered during delivery hours
Free shipping at X price
Zip code check before moving through check out
code to allow zip code check elsewhere in shopify store
Easy/Intuitive to use
