On demand delivery Logistics

Job ID: 36731519

Budget: $250 – $750 USD

I want to make a logistic mobile app where we can deliver products and goods from stores right away, like food delivery.
We have many stores and online stores, these stores sell their products either on big websites like amazon or on their own websites, my idea is that to link my logistic company to their website, so when a customer order from the store website a driver will go right away and pick up the order from the store and deliver it to the customer, so what we are trying to do is that to make the delivery (on delivery delivery) instead of waiting for one or two days for delivery. We want to make the delivery ASAP which you can get the delivery from about 30-60 mins from the order time. It’s like delivering food. That how we want to do it, and we need someone in logistics who is very good and can right a plan of how this thing can be possible and it can be operated. (this idea is more possible to deliver within the same city)
What i am looking for is:
How can we make that possible?
How much should we charge per delivery?
How about stores who are in one city and they want to deliver to different cities?

I need a creative experienced person who can make that possible in logistics
