SendHub - simply delivered

Send-Hub is a communication app that connects delivery guys with customers.
Customers such as restaurant or attorney use this app to place order to send their items such as food or document,  senders (delivery guys) use this app to locate orders nearby and deliver them.
The basic workflow is:
1. users sign up as either customer or sender.
2. a customer can add a sending order by specifying category (such as food, document, etc.) and destination address.
3. a sender can search active orders being placed by customers nearby and bid for them.
4. customer choose one out of the senders who bid for the order.
5. sender who won the bid can pick up the item from the customer and deliver it.
