You have two type of workers:
1) Booker - comission based salary
2) Salesmen (this case it sounds better for customers if you call the salesmen by name of "broker").
The booker nakes appointments for salesmen and the salesmen sells.
This is very much a game of numbers but also personal skills are good to have. The good news is, one can learn to be a good salesman within 1-2 years if one is willing to put an effort on the learning.
You need to have a psychological sensitivity (to see which kind of arguments will sell this particular person).
Bad sellers sell usually 10 % of their appointments.
Good sellers close 50 % or more of their appointments.
In the beginning the learning curve is pretty steep, but it requires tons of contacts. The more contacts, the more sells.
I suggest to target millionaires since they can afford even lose 30 000+ usd (it is only 3+ % of their networth and often they have used to have some fluctuation in their portfolios).
The most important thing is to be honest and straight. I am sure the customer will ask at some point what are the risks, just tell him the probability of 75 % it will go to 0 and you lose 3 % of your portfolio value (which is not bad for him even if the absolute values might sound bad for us).
Honesty also pays off. When Monero is more developed, those people might be willing to buy even more coins from you.
Also you might offer two type of deals: 1) you agree on a fixed price you sell the coins 2) you marketbuy the coins but you substact or add your comission.
Since most of the sellers are bad in the beginning, 10-20 % comission is perhaps good to take (if you agree the fixed price you need to evaluate the slippage + your comission).
For salesmen I cannot emphasize more to prepare well for the appointment (perhaps the booker can take notes what they were talking about on the phone etc - in this way you can learn what is important probably for the customer).
The good news is: In the world there are more dollar-millionaires than never before in entire human history so there certainly is potential now if never.
That is true. There are a lot of people now with a lot of stupid money. Hooray quantitative easing.
I do not know if it is stupid money.
Usually the stupid people end up to poverty if they have had money at some point.
You are not able to make any money unless you do not take sometimes some serious risk. Monero currently is such risk. As stated here several times, the probability to fail is high but it is not certainity. And if it doesn't fail, it will go through the roof at some point.
Those rich people are well aware that they make money by taking risks (especially if their way to make the fortune is not inheritance but entrepreneurship). Monero is a speculation which only smart people does since the estimate value is high. On the contrary, the masses are stupid and they are gambling the unfair gambles (such as lotteries, futures, options etc).
