Amazon.com Inc’s call for entrepreneurs to help expand its package-delivery network is a cry for help. 

The online retailer’s Prime service, offering free two-day shipping on many goods for US$119 a year, is spurring annual growth of 25% on product sales. As other retailers also fuel the surge of e-commerce, United Parcel Service Inc, FedEx Corp and the US Postal Service are straining under the load.
