Wedding Sponsors

Hi, We are a family of six. We have been engaged for over two years now. We have been holding our wedding off due to money. We read about the wedding that was sponsored by Dr. Pepper and thought we would try to get some help on our wedding. Were not asking for a $10,000 wedding. Just a little help with the dress, cake or reception. When my dad found out my mom was having me he denied me from the start. When I turned 16 I finally confronted him. For two years after that I got a card. That ended real quick. He hasn`t even meet his grandkids. It`s really sad as my oldest asks me about him. My fiance`s dad has passed away. Both our mom`s stuggle everyday so they can`t help us. If anyone has any suggestions please let me know. I want to ask my dad for help but don`t know how to go about it. HELP!!! I also read other comments on this site and please if you don`t have anything nice to say please don`t respond. Thanks in advance
