Yeah I think so. I'm not going to hire a performer - I think the numbers can be achieved without such capital expenditure.
But your second point was very good.
One of my key methods is to start by only inviting a very small amount of people, and downplay the event such that it is expected to be small and exclusive. This exclusive group are all close friends who are gatekeepers - either social leaders or very hot or the kind of people that otherwise attract lots of other people. When you are sure this group is coming, you'll find others enquire and you can open up to a few wider social groups. Before you know it, you've multiplied 10 people to 50.
With 50, you can multiply the numbers further - numbers make more numbers.
During these small stages, people come because they see that they can gain some sort of personal value - e.g. friends/girls/performer like you said.
However, the KEY is that you grow your number of attendees due to this personal value, UNTIL the point where there are SO MANY numbers, that the value no longer becomes friends/girls/performer, but the mere fact that there are a lot of people coming. How many times have you heard the conversation:
Bob: "Hey you coming to this party?"
Gill: "Uh maybe who's going?"
Bob: "XX and YY are going"
Gill: "Oh cool in that case I'll give em a call I might come."
That's good, but isn't it even better if it goes like this?
Bob: "Hey you coming to this party?"
Gill: "Uh maybe who's going?
Bob: "Seems like everyone is! I don't want to miss out."
Gill: "Really? When is it? Do I need tickets?"
Value breeds more value, numbers breed more numbers. This strategy alone can get a good 100 people I reckon, depending on your general popularity in life.
Of course, there are other strategies equally as good which I'll divulge, if people give me some good ideas first
