I would say that you need to get a job, and that job is your startup.

The key thing is that you say that you are at the point where you can get some cash. Based on the attitude I've seen from angel investors and incubators, once you start to raise money it's essential that you're full time on your startup. In fact, you need to have at least one co-founder who is also full time. If you have access to some capital, get it and use the minimum possible to support yourself while you create your MVP.

If the MVP fails, pull the plug and get a day job. Entrepreneurs are dedicated and therefore very employable. You can work on your next idea while you work a regular job, and then again, if you get to the point where you can raise money, go full time on the next startup.
