请大家帮忙修改下这段英文 写的对吗 “Time is too tight,we will try to book the latest saling date.
Time is too tight,we will try to book the latest saling date and till now we are still waiting the book confirmation from our agent.the best ETD would be on next early week.
Since the booked vessel schedule is very urgent in recent days,it is hardly for us to get the vessel space due to the busy bookings to shipping lines to Jakata.therefore,please advise if we can prebook the shipping space when we received your demand.then we will get the shipment at an earlier date.
