If I were you I would do following:
1. If you have worked in a big Co for 7 years then I assume you have some money saved up.(Or some discretionary savings for entrepreneurial activities?)
2. I would allocate around 20k from my saving and hire somebody(a developer or two) from toptal or codementor and then build the MVP. I am sure you will find some great developers on those sites who won't mind building the MPV if you pay them per hour. You can even negotiate a lump sum for the entire MVP project.
3. Then start aggressively acquiring users.
4. Next convince the working developers to come onboard as a full time and become technical-cofounder.
I am sure there are few caveats to this approach
This is my personal suggestions though. Take it with a grain of salt.
