Group visit HKG Zhuhai MACAU in one day

My family(9 adults) stay at TST area. Plan to visit Zhuhai by Bus pass the bridge. Then sightseeing at New Yuan Ming Palace, Fisher Girl Statute, and back to Gongbei port. Pass to Venetian Hotel.
1. What is the best way if we want to catch bus to pass HKZMB with cheapest price.
2. Where is the bus stop at ZH? Is it stop direct to immigration border to ZH? Or we must catch a bus to immigration?
3. From ZH port what number of bus we can use to New Yuan Ming Palace, Fisher Statute and back to Gong Bei port?
4. Is the Venetian Hotel shuttle bus (free) are available in Gong Bei port to Macau? Thank you
