Help us move please

Hi there loves. I recently became the guardian of my niece and nephew. Their mother, my older sister unfortunately has a problem with drugs and to keep them out of the system , i am now taking care of them. The 3 of us currently reside in my 1 bedroom apartment . This was ok until this morning , a “concerned” neighbor informed the condo association and I received a warning. I have to either upgrade to at least a 2 bedroom apartment or we all have to leave. I have 30 days from today to achieve this with very limited funds and help. If you can help , please do. This is already a hard time for them and I don’t want them to be split up . Life has always been hard for them with my sister as a parent. I would really be thankful for any support and help I can get. Thank you for listening and reading without judgement.
