If you want to pay yourselves even $50k/year you're going to need a few hundred grand. You could start with friends and family. But it does sound like some sort of accelerator might be a decent idea. Are there any in your vicinity (or in vicinities you would consider moving)? The accelerator would ideally help you with funding and pretty much every question you're asking.

If you do go the outside investor route, be careful with your pitch. Most startup investors are wary of near term cash flow & profits. That indicates a small return for them.
