1 have you looked into medicaid/state sponsored assistance?
2 my ABA therepists do inhome therapy. and i can ask them to add a behavior routine/program for appropraite behavior.
3 if you want to work on it at home by yourself you should start with a toy. show him how to treat the toy appropriately. then when your comfortable with that then you can move on to treating a pet (one that can handle inevitable abuse, so a med-lg sized dog, or similar sized animals ie pig, sheep goat, etc works well) with care. and then bringing hte sister into the program when he hasnt misbehaved in a while.

yes your daughter will be with your son ALOT inbetween time but you should seperate them when behaviors start to escalate. im actually more worried about my NT (possible other non autism issues) girl beating up on my autie son.
