Local delivery app alternatives

currently using Zapiet for Local Deliveries and like it for the most part but there a couple key features I would love that are not supported by the app. I am wondering if anyone’s undertaken the project of building a custom delivery app and if they think it was worth it. Alternatively, if any of the other delivery apps either support these features or their developers offer customization services. (Zapiet sadly does not). 

The features are:

1. The ability to charge an extra fee for same-day orders. 
2. The ability to charge more for certain time slots. Eg 9am - 5 pm is one price but if you need a more narrow window like 9am-10am it’s a higher price.
