You're welcome and welcome to entrepreneurship. :) Another option, often not considered, depending on where you are in your career is to join a very early stage startup that is doing something in your domain, for 1-2 years. This may or may not be an option for you depending on your own factors, but that is a good option as it helps people migrate from the large company mindset to a startup mindset. Also, it helps extend your network with the right kind of people that may help when you go on your own.
