Are you paying yourselves salaries? Do you have an actual office? Benefits? etc? I would suggest that you not get ahead of yourself with "making it big" and instead focus on making it a solid business. Get to the point where you're paying yourselves and everyone who works for you a market rate salary and benefits, and you have office space, and you're cash balance is growing. Basically this is the classic definition…
No salaries, no office. My two cofounders and I have been throwing everything we've got into this; we're all broke. Our business model requires people actively maintaining property listings at each school, and then growing student traffic at that school and then, once we're established, securing advertisement deals. Our rationale behind raising funding is that we can either cut corners and struggle and keep adding on…
To throw in my 2c, you shouldn't have to land the huge advertising deals and spread to fifty campuses just to make enough money to pay the three of you guys. If you require a nationwide presence just to make enough money to pay three salaries, the business doesn't work. But it doesn't sound like that is the case, so it should be doable to reach a level of income where you can pay yourselves without expanding too much yet. Then grow.
