Making room for our family

Hello, please help us raise money to convert our garage into 2 bedrooms and a bathroom. We have 4 kids and only a 2 bedroom home. My two step children need their own rooms when they are with us. Currently the 3 oldest share a room and it is working out, but not for much longer. My husband is a disabled veteran with a lot of health issues so I'm going to be doing some of the construction myself (at least what I can teach myself). Please help us get this project started so we have enough room for our family.
