"Start on a Monday, have a date by Saturday"...makes it sound like a website done by enterprise software peddlers (or AdultFriendFinder :) ). Something a bit less precise and goal oriented, and more fluid, to go with the concept of mingling perhaps? To "mingle" somehow makes me think of stepping off my routine treadmill and getting to know people in a lazy, smell-the-flowers-along-the-way setting.
