What are your chances? I would say pretty darn good!
I love your story of mobile health, and the efforts you have ALREADY made to make this happen, plus the very honest admission that you need help. You seem like someone with ambition, and vision, but who also keeps things practical. Plus your goals will ultimately help others, and this is something that Bschools LOVE. So use these wonderful stories to build your narrative as you present yourself tot he AdCom, and you should do fine!
I would however though maybe add one of two more schools to your list. There are a lot of really amazing programs in the top 20, and ones that specialize in both entrepreneurship and in Health/Pharma...
As for when to start working? Normally before you start writing. A good consultant can also just help you answer your questions about strategy: where to apply and when, and why... Plus will help you get started on your school research, and well, basically everything.
