This is only the pilot and they're trying to get the series greenlit.

Uhhh considering the amount of views and the hype it generated, I hope they reached their goal?
But in terms of production, well, no idea how long it will take. If they want to make a whole season with episodes on this quality level, then I can imagine you might have to wait 1~2 years minimum? But that's just my uninformed opinion, take it with a grain of salt. Might be more, might be less.
