Help them get vaccinated & dewormed

I took in these box of barely two week old puppies abandoned in a cardboard box near the dumpster at my workplace. It's the rainy season now and it pours almost every day. One of the little guys went missing when i went back to get them.

Most of the animal shelters advised me to get their vaccinated, dewormed & foster them until at least two months old before giving them up so that they have a better chance at survival at the shelters. The cost for vaccination and deworming is approximately 50 (before tax) and the puppy milk around 80 (20 x 4 packs for 2 mths care) and the feeding bottles around 8. I have 4 rescue dogs of my own so any amount would be appreciated to help these little creatures to keep going.

Thank you so much.
