Recommended Travel Agent in HK

Hi, I'm Santosa from Indonesia.
I understand that I will be exempted from applying for a visa if I join tourist group at Hong Kong and Macao organized by registered travel agencies in Hong Kong and Macao to visit the Pearl River Delta region (Guangzhou, Shenzhen, Zhuhai, Foshan, Dongguan, Zhongshan, Zhaoqing, Huzhou Municipalities) for tourism and stay up to 6 days.

Do you have recommended travel agent in HK which can organized my travel to Shenzen please ? Many thanks...
