With anything anywhere, you need to consider whether there is any demand.
Do you know at least 10 people who also want to see a new Milonga start up? Just saying, "Yea, great idea" is not enough. Do these 10 people want it enough to pool money to create a fund that will pay you to rent space for the first year worth of parties?
Yes, you might think you are willing to do all the work and fund a few dances hoping to make earn back what you spent. But if you don't know others who want this enough to pay a bit in advance, you will likely find you do not break even. You'll also have a hard time getting any "word of mouth" advertising. On the other hand, if you identify a group of people who are willing to pay in advance to get it to start, it has a chance of taking off. Most of these people will come to the first few milongas, they might bring a few friends and so on. Their presence will make it a somewhat active miloga that can attract other dancers.
In contrast, a Milonga with only two or three couples at the first few events is probably going to have trouble taking off. (Not to mention you will bleed money.)
In the US, if you were to do this, you might eventually want to file papers for some sort of actual club that can have it's own bank account, insurance and so on. You could have club dues which gives some amount of stable revenue.
(Yes. Some other organizers might resent you popping up. But to some extent, that's a hazard of business.)
Other people have brought up useful milonga specific suggestions. But some advice is for startin anything, anywhere.
