Laravel Website Upgrade and API Integration

My existing Laravel website has several upgrade needs to boost its functionality and performance.

The budget is $500.00, nothing else will be discussed. Timeframe is 15 days.

Here's a detailed breakdown of the tasks:

- Set up daily sales exports to QuickBooks.
- Update category API calls.

- Ensure prices and inventory refresh every 60 minutes.
- Exclude specific items completely from the site.
- Configure auto-emails for order information and tracking.
- Enable individual customer and order queries.
- Implement a lost cart recovery system.

Ideal candidates for this project should have:
