Help Loni get divorce attorney

Tyler, Loni's soon to be ex, is sueing her for divorce. He lists their assets at over 500k and wants Loni to sign divorce papers that give her less than one tenth of the assets and he keeps everything including their house. He won't give her any money for food or gas and is blackmailing her to sign this crap. She saw an attorney and he's ready to get her fair share but wants a retainer of $2500. The other $500 is to get her some food money until a hold can be put on Tyler's accounts and get her some spousal support. She has been a stay at home mom for ten years raising two fantastic kids and has never had a debit card or checking account. She has spent  ten years asking Tyler for every cent she needed. Please help me help her and her kids.
