How do I actually make money wholesaling?

[Mickayla Smith]

Looked into wholesaling to start out with in the real estate investing industry. From my understanding, as a wholesaler, you are getting paid to find somebody a good deal. If this is correct, how exactly do you get that money? For example, if you find a deal for $10,000 and know a buyer that would be interested and sell it to that buyer for $12,000, that $2,000 goes to you as the deal finder but how exactly do you get that $2,000? Do you simply say in the open "I'm charging you $2,000 for finding this deal" and they write two separate checks? Maybe I am completely off on wholesaling but I was really interested in it after I heard a couple podcasts about it, so I wanted to get clarification before I go out searching for buyers and deals. 

Thanks!
