Need some high-level advice on app development

I have an app idea that I eventually want to be created as an iOS and Android app but need to be web app first and foremost. I only took a C++ class one time. I'm not looking to make this thing myself. I'm going to have to get help to be successful. I just literally have no idea how to get started. I know it is going to be expensive. I know it has the potential to get REALLY expensive.

Are there any resources anyone can direct me too? I have a good business sense and am pretty tech savvy.

I need direction on things like:

• Development Platforms to use
• Coding languages to leverage
• Start ups
• Funding (crowdsourced/angels/etc)
• Legal advice: patent, liability, etc
• Where to hire good talent

This is my first run at brainstorming so I'm consulting the hive mind. Any thoughts/ideas are greatly appreciated.

I'll probably eventually break out and ask for much more specific help in time, but I got to get this thing off the ground. My goal is to help more than a million people. If I could even break-even doing it, it would be worth it to me.
