Edu left teaching in 1930 and started a career as a clerk with the Africa Oil and Nuts Company, a firm that had a business alliance with Holland West Africa[9] and was involved in buying palm produce at Epe. In 1933, he was posted to Apapa as a shipping clerk with Holland West Africa. By 1945, he had risen to a managerial level. As a manager, he organized the Dutch shipping line's offices in the country and helped in expanding the business to other coastal cities. Figuring out there were affordable untapped prospects in the Nigerian shipping industry, he left Holland West Africa Lines and founded his firm. Using his prior experience in the shipping industry, he found himself a niche in ship handling and stevedoring. He later expanded the venture into timber and other commodities. In the post war period, he was a food contractor to private, government, and European agencies. He also delved into the oil haulage business working as a contractor for British Petroleum. Edu was the chairman of British Petroleum, Nigeria when the firm was nationalized and had its name changed to African Petroleum by the Obasanjo regime. In partnership with T.A. Braithwaite and Munich Re-Insurance, he set up an insurance firm, African Alliance.
In the 1950s, Edu was a member of the expatriate-dominated Lagos Chamber of Commerce, as a member, he became acquainted with the law firm of Irving and Bonnar which acted as an advisory firm to foreign businesses scouting for opportunities in the country. Through Irving and Bonnar, he secured board seats with Blackwood Hodge Nigeria, plumbing and electrical firm, Haden Nigeria, and Glaxo Nigeria. He was also a board member of the Federal Industrial Loans Board from 1954 to 1959. In 1963, he was elected president of the Lagos Chamber of Commerce. Edu's voyage on the high seas of entrepreneurship started as a ship chandelier, food contractor, and timber trader. He was successful in business. He expanded his business interest in the early 1950s to include such areas as transport which he named Slee Transport Limited. This company majored in oil haulage and transportation of petroleum products. From the 1950s to the end of the First Republic, Slee Transport Limited was a major haulage contractor for British Petroleum.[10]
He grieved that he had to witness the contemporary deterioration in the state of Nigeria's economy, governance, and international relations. Nigeria's suspension from the Commonwealth during the General Sani Abacha tenure as military head of state was particularly bitter to him as he was actively involved in the Commonwealth Chambers of Commerce in his capacity as the Chairman of the Nigerian Chapter of the Royal Commonwealth Society for decades.[10]
