I would post on Facebook because more people and rescues could see your post there and help you and the kitten.
Take it to the shelter they will give it shots and a home
You can definitely take the kitten to the shelter or Google a Kitten rescue in your area. But do it soon a kitten that little can't be without nourishment too long! Good luck!
You can get bottle and kitten food at pet store to feed it. Pet store will probably know a kitten rescue, too
