You won't need any support until people hear about you. First get your ideas, then compile a team of people who have the technical skills. Write up your concert and detailed whitepaper while the tech guys build the infrastructure. When you're ready, you can get people for community support.
Yeah, but what I'm asking is... Imagine the first day when I am announcing everything, talking to media, getting some first ads, etc., so I'm already getting people hear about me. My question is - do usually people start asking questions in an active manner from the very first day, which means I need multiple support/community guys from the very beginning, or is there some lag before the support team high load begins, i.e. people are researching, thinking, and only after that start asking questions, in like 2 weeks?
