I would still say to do a 25% change once in the morning, and then another in the evening.
I also suggest, again, that you find new homes for all of your fish today if at all possible. A pet shop may take them for you. You may even be able to sell them to a tropical fish store. If you give away or sell your fish, you could do less changes per day and let the tank cycle at a more stable rate, and not kill your fish.
If you keep your fish, I suggest you get some stuff to protect them during a fish in cycle. They're not perfect, no, but they should block the worst of it. I'm not sure what they're called since I never recommend them, I usually tell people to just get rid of the fish or don't get any until a cycle is complete as it's cruel to do otherwise, but YOU got stuck between a rock and a hard place. Go to your local LFS or a Pestmart/Petco and look in the fish water care section, they have a lot of stuff that helps block the toxins.
I also suggest you use Seachem Prime, if you aren't already. It neutralizes the toxins that can hurt your fish and removes ammonia. Use it for each water change. It's what I use for mine.
Can you test your tap water and put up the numbers for us? A lot of this may actually depend on your tap water, and it'll help to know. If you have ammonia in your tap, as most places do, Prime is the absolute best water treatment you can use for the tank. Otherwise you're just dumping more ammonia into the tank. Some also have nitrates or nitrites. Depends where you live.
