How big of a list before I should expect a deal?

[Danny Leyva]

How big does my list of people i have to market to have to be in order for it to be highly favorable that i will have a deal out of that? 5k? 10k? 20k? what are the most prospects you have ran through before getting a deal? should i expect a deal out of every 2 thousand prospects? 5 thousand? 7 thousand? thanks!
