don’t be afraid just get some seeds & start your journey. don’t expect a trophy your first time & you’ll probably be surprised & impressed after a bit of trial and error.
the TLC homegrowers put in is mostly why 1st-time growers are astounded that the seeds from an unimpressive 1/8th of whatever-weed produce some tasty homegrown.
there’s an old saying ‘speed costs money - how fast do you want to go?’ and it holds true for weed somewhat but not really. assume about 1k USD will get you an excellent setup & 200 a mediocre one but a grow nonetheless. Try to buy things that can be re-purposed as you progress-- i.e. a small light to start can be used for clones & starts foreverish.
Since you stated you need qty ASAP(my sympathies, you’ll get there), definitely get some autoflower varieties, but also start some photoperiods if you can. Plant guerilla outdoor if you can…hands-free, no-water stuff.
And expect some flops & failures but that’s just like riding a bicycle or anything else…most of us stall the car before mastering the clutch.
