Help finish build a house for a family of 15

My grandparents build a 3 roomed house more than 50 years ago,the house is old and even falling,My family is as follows-My grandmother,grantfather,my mom,2 aunts,2 uncles,my brother,5 cousins,my son amd myself.Only me and my other aunt work,she works as a domestic worker,so the whole family relys on me and my grandparents grant.So in 2013 I decided to extent the house that we were all staying in as it was too small,I started the project in November 2013 even today it is still not finished,but it only needs few things,like few roofing material,window glasses and it also needs to be plastered.I really trymy best to finish it but it is not easy as i also need to provide for the family every month.My father passed away in July 2012,few months after that my mother got sick,she has arthritis so i also have to providr for her medications as well.I dream is to finish the house before the end of this year.I would really appreciate and i will be grateful if there are people out there who will be willing to help us.Thanks in advance.
