We need an application like Uber but the clients order gas and water not taxi. also drivers are gas or water providers. WE already have simple Uber codes that can be used in this application.
At registeration, can be client or provider; provider can be water or gas provider. At client login, can choice water or gas. So they can order gas or water.
The customer will see time of delivery , location of delivery, etc.. The customer can select the product and quantity.
The client order service (water/gas) and then the closer driver (service provider) will pickup order and deliver it to customer.
