Isn't this basically how startups work?
I built a full app to 1000 users in 2 weeks, to first payment and 5000 users a month after that. Keto recipes where we'd sell substitution ingredients.
Hardcoded the data. Didn't even have a shopping cart or payment gateway. We'd just query ordered items by the user phone number, and then give our bank details so that they could transfer.
Eventually we fixed it in a few months. But it was sufficiently complex, lots of content, low margins, physical items, which I still think is pretty impressive to get off the ground in a couple of months.
