A Georgia-based company is adding 100 jobs on the Alabama coast. Rural Sourcing Inc. of Atlanta says it's opening a new software development center in Mobile. The operation will open on Feb. 1 in a temporary location in downtown Mobile while the company looks for a permanent home in the port city. Rural Sourcing Inc. aims to provide a cost-effective way for companies to develop software in the United States rather than sending the work overseas to countries like China or India. The company already has software centers in Augusta, Ga., and Jonesboro, Ark. Its goal is to have a dozen such operations and 3,000 U.S.-based employees. Rural Sourcing says its clients include Coca-Cola and Sony.
