Congrats Tammie, you posted the 5,000th review on this site!
Now on the logline:
The reception lounge has nothing to do with the heart of this story (according to the rest of the logline), so just cut any mention of it.
Also cut the mention of the CBD, it is irrelevant - and confusing as appears above. Alex, it means "Central Business District"
This story is about an event manager who must save his family from financial ruin and shame but we need to have an idea HOW. What is this movie going to look like? Is it a thriller where the event manager has to take on the crooks in the business? Or - more likely - a drama? And then how do you make this story interesting?
You indicate there is conflict between the event manager and his father but why? Is the father conservative and against modern business practices? Still, I fail to see any cinematic angle here.
