SOAP service to ouput Order, Line item and Customer info

I would like to create a SOAP SERVICE on my drupal commerce website to enable Another application to Read and update the orders that are made in commerce.

I have already installed the services module and all i need is to be able to configure it such that an external application can connect to drupal commerce and read the latest orders and and change the (order status) to "order accepted".

I need 3 sets of information to be read and updated

1. Service Order
   • Order ID
   • Customer ID
   • Shipping Address
   • Customer name
   • Order Status
2. Service Customer
   • Customer ID
   • Customer Name
   • Customer Billing Address
   • Customer Phone
   • Customer imported Status
3. Service Order Line Item
   • Order ID
   • Line Item Number
   • Line Item SKU
   • Quantity
   • Price
