Self plug here but for the low low price of FREE, give MapTool a try and with all that money you'll save, you can spend it on Hero Lab!
But seriously, I've been told we have a great community of people so if you feel a little overwhelmed with a big blank grassy map, hit us up on Discord! Chances are, other people asked the same question(s) and willing to help new players get started (or search through the history for answers). We also have a forums if that's still your thing.
