Clean the bar and do front squats
you can also do body squats - there are tons of variations you can do with body squats.
You can try zercher squats.
i have same problem, i dont have a squat rack so i can only squat what i can lift above my head and onto my shoulders, so i squat my 1 rep max on the shoulder press, 3 sets of 60 reps.
like said before, front squats. Also try jefferson squats, they are old school.

WHITE WHALE!
do half the movement for a clean and press, then front squat the weight. its like a dead that transitions to an upright row, while moving your elbows under the bar.

I have to say that Zerchers are your best option here. You can start from the floor or you can go to home depot and buy a couple heavy saw horses to set the bar on to start from.
