Sponsor My Wedding

I need help. My fiancee and I have been planning a wedding for 100 close friends and family at our home. Both of our families are all from out of state. Unfortunately, every time we set a date something financially comes up. He is a hard working man that provides all of his family`s needs and always puts his family first and his needs last. As of this year, I have lost my job and so has he. He does odd jobs here and there. Nevertheless, he wants me to have the quiet backyard house wedding but we cant afford it. If he cant give me 100% he`d rather not give me at all. We have been together for 6 years, 6 children ( 3 each) a granddaughter and a very ill father in law, we would love to get married before his father passes. His mother passed without seeing us married and he also doesnt want his dad to go without enjoy our day. Therefore, we are looking for sponsors for a wedding. I already have my dress and we obviously have the venue (our home). We need help with everything. Can someone advise PLEASE....Thank you and God Bless.
