After collecting enough money, he bought a wagon to expand his business. He managed to build a business network and eventually gain customers? confidence. Besides that, Baharudin was also encouraged and trained by his late father on how to deal with small business of key limes in Chow Kit Market Road. In 1975, he has been able to buy a mix coffee processing machine and a shop lot house at No. 9, Greenwood Park that serves as a coffee processor factory (Arshad Coffee Mix).
