I am looking for an app developer for my food delivery app. Can anyone help?

Everyone must have heard about famous food delivery apps such as Grub Hub and Door Dash. Being a food lover myself, I use apps like these on daily basis. However, I have noticed a couple of flaws in the operations. Now, utilizing my entrepreneurial skills, I want to develop my personal food delivery company with some unique features. Someone recommended me to hire custom mobile app development company to get the app created. Who can help me find a good one?
