At this point, you have to step back and re-evaluate your plan. The possibility for you to raise money this kind of money for what is a non-scalable, hyper-local business are close to zero.

I suggest you focus on making money so that you are not dependent on your wife's income and then:
1) Create a business plan for your concept. That will show you if your idea is viable from a financial perspective. Do the research yourself and do not get fooled by your passion for your idea. Be totally rational when doing the numbers , not optimistic.
2) If the numbers make sense, then start trying to raise funds by approaching people in your network.
3) Do not spend anymore money for work that you could and must do yourself.
