Guys please give me some feedback. We are about to do something "crazy": leave our 6 figures jobs to start our own shop. We are 2 engineers with 10/11 years of experience each and we love the idea of running our own consulting company focused on Kubernetes. We both have worked for big tech companies, startups and currently working for a hedge fund. We managed/automated large scale systems (our current datacenter have over 40k instances - around 2.5MLN CPUs 160kTB of memory across all machines), we both are skilled system and software engineers! We are engineers/architects, we have never done sales/marketing/social media. What do you think it's the best way to find customers? Any suggestion for someone who is starting now?
