• The green movement is helping new businesses sprout up all over the Metroplex. ... Also out of the gate is Go Green Couriers. Formed by four North Texas friends with extensive courier experience, including Tony Hormillosa, the company uses only hybrid vehicles and bike messengers. It also relies on a paperless ordering and billing system. Hormillosa says traditional courier services create “a ridiculous waste of resources.” He and his Go Green partners are betting that customers will prefer an eco-friendly alternative. “Dallas is one of the largest cities that’s going green,” he says. “With the upward trend of gas prices, it just makes sense.” (Full disclosure: Hormillosa is the hubby of DBJ’s editorial assistant Shashana Pearson-Hormillosa.)
