Having trouble understanding.
She bites everyone? What does this mean? Everyone in the household, or people who are friends and over often, or people you do not even know?
In a malicious way? It almost sounds like you are saying it is not malicious, but these are bites? Is she breaking the skin? Is this unwanted mouthy behavior, or are you going to the ER every day to get stitched up?
It sounds almost like she is using the biting to engage with you, and when you are playing with her, she gets over-stimulated and starts biting. How do you play with her?
You can't afford proper training. Well, that's not good enough. If you can afford a vet, then you can afford training. You own a dog that is your responsibility. Do you have a cell phone? Drop that and buy a set of training classes. Do you pay for internet? Cable? Do you eat out, ever? There are so many things folks take as necessary or as a given. Your dog is your responsibility and before she becomes a liability, you need to get her trained. You are not doing well enough on your own. You need to do what it takes to get your dog what you need.
The number one reason dogs get dumped and killed at shelters when they are your pup's age is because their owners dropped the ball and did not bother to train them. So you pup has a disease that will take her life that is totally curable. If she was bleeding and needed medicine from the vet or she was going to die, would you get the money and take her to the vet or let her die?
Get a trainer, someone who knows what they are doing. And don't wait. Take peanut butter and jelly sandwiches to work for lunch, eat raman noodles for dinner if that is what it takes. It is all about priorities. This one is fixable. This one is on you. Please do the responsible thing.
