A Minnesota-based business support company has decided to expand in Iowa again, just weeks after buying out another Iowa business. Last week, Marco announced the purchase of Midwest Office Automations and it's two offices in Storm Lake and Sioux City. With the purchase, Marco also announced it will be retaining the company's 21 employees. Earlier this month, Marco announced the purchase Mason City-based Business Systems and the retaining of all 75 of its employees. Business Systems has six offices in Iowa, including one in Fort Dodge. With Wednesday's announcement, this marks the 4th acquisition Marco has made in the past five months, adding 130 employees in the process.
