Hi,
I own K&C Fence Company and need a Power Apps developer to build a KPI Scorecard and Quarterly Rocks app using Power Apps and SharePoint.
The SharePoint lists are already created:
Departments

Rocks
System Settings
What I need:
Departments
Add, edit, delete departments
KPIs
Add, edit, delete KPIs

Unit

Frequency (Weekly or Monthly)
Sort Order
KPI Readings
Weekly KPIs support W1–W52
Monthly KPIs support Jan–Dec
Add, edit, delete readings
Notes

Graded Score

UI Requirements
Very simple
Easy for non-technical users
Desktop and mobile friendly
Clean dashboard
Large buttons
Simple navigation
Delete Confirmation
Before deleting any record, display a confirmation popup.

Message:
"Are you sure you want to delete this item?"

Buttons:
- Yes, Delete
- No, Cancel

Do not allow one-click deletion.

Apply this confirmation to:

- Departments
- KPIs
- KPI Readings
- Rocks

If a Department contains KPIs, warn the user that deleting the Department may affect related KPIs.

If a KPI contains KPI Readings, warn the user that deleting the KPI may affect related KPI Readings.

I am looking for someone who has built Power Apps before and can complete this without me having to manage the technical details.
Please answer:
How many Power Apps projects have you built?
How many hours do you estimate this will take?
Fixed-price cost?
How long until completed?
Can you show examples of similar Power Apps you have built?
Thank you.
