Yikes, it seems like you're in a spot. If the kittens haven't eaten that whole time it is absolutely urgent that you feed them.
A rescue might not be able to take them right NOW, and they need to eat. At this point they are already at a high risk because they've been without food for so long.
Step one is getting formula for them as a temporary measure at least. You'll also need:
-kitten bottle kit (they're cheap, and even if you can surrender the kittens the rescue could probably use more supplies, so it's a win-win)
-food scale (you'll need to weigh them ASAP and then again a few hours after feeding. Kittens who are loosing weight are at very high risk)
-Dropper/syringe (to get them started eating, kittens will very rarely take to a bottle quickly)
That's the absolute minimum, there's a bunch of other things that would come in handy (paper towels, for example) but they're either things you're likely to have around the house, or that aren't worth getting if your plan is to surrender the kittens.
As Ami and Carmel said kittens that age need to eat every 2 hours. In this situation I'd add a tiny little bit (1 tsp or less) of corn syrup to a large batch of kitten formula. They'll need a bit of extra sugar after going without for so long.
Another thing that you need to do now is check them for dehydration. Gently pinch and lift the flap of skin between their shoulders (the scruff) and see how quickly it shrinks back to the right shape. If it's quick and instantly goes back to the way it should look that's perfect. If it slowly slowly shrinks back and a little ridge stays for even a few seconds that kitten is dehydrated, which is a very dangerous situation for kittens.
They will probably also need to go to the bathroom, since kittens that age can't eliminate by themselves. Use a moistened paper towel to gently rub their backsides to help them to eliminate. It shouldn't take much, since they're probably full to bursting.
If you can't commit to round the clock feedings then you should start contacting rescues in your area. After you tell them what has happened ask them: What will you do with the kittens. Many kill shelters simply don't have room or time to care for the babies and with euthanize them. They usually won't lie about it though...but I'd start with rescues rather than shelters if possible.
A rescue worker may also be able to give you tips, or maybe even hands on help, getting started caring for these babies.
Let us know how it goes!!! Good luck!
