Hazes are not IMHO the ideal commercial strain. The flower time is long enough that you can run into issues such as becoming rootbound, too tall, or soil pH plummeting from overfert, salting, or simply the lime being used up.
Go for a classic commercial strain such as NL, PPP, Afghani, Skunk1, BigBud, etc.
Start small. Really. Try your hand at growing, because you WILL make mistakes. We all do. This will give you the time to grow out a few big fat mother plants, which you absolutely NEED if you have commercial aspirations. Vegging 2 months from seed is appropriate, but remember, you will have to start twice the plants you need, since about half will be male. So your plant count becomes a burden.

And please stop asking how much yield. How long is a piece of string? No one can answer that. You could get pests or disease, or make mistakes that wipe out your whole crop. You could have adequate conditions and average yield. You could do very well and if you're really dialed in, maybe you will hit 0.5 gwm. MAYBE.
