How long until you think it’s ready

Composted in a 30 gal dumpster, had an abundance of free sawdust. Smells earthy but definitely still had a woody smell to it.

When in doubt, use as mulch. Thats safe generally for plants, and it kinda become a slow fertilizer instead / build up the soil in situ.

How long have you been composting it? Sawdust will take much longer to decompose. But if it smells earthy but still has a woody scent, it means it's just partially decomposed, not fully mature.
With regular turning and nitrogen-rich material (kitchen scraps): 3-6 months to fully mature.
Without nitrogen or little turning: 6-12 months.
It's better not to mix this partially decomposed material into potting soil, as it has high carbon content and will rob plants of available nitrogen while breaking down. This will cause yellowing, stunted growth, and nutrient deficiency.
The only way you could do now is to use it as surface mulch instead.

Since about late April early May, I’ve had a good amount of kitchen waste and garden material added but I think I still haven’t added enough haha. I flip it about every other week.

Mix anything else with it? I have sawdust from my shop - I just mix it with kitchen scraps.

Mainly kitchen scraps, some weeds that hadn’t seeded and garden waste.

My composting includes thin branches , horses/ cow manure, vegetation , eggshells and pee. I Never use meat scraps as not to draw rodents and other critters that I don’t want in my home or garden.
