Weddingbee boards

I am a McKinney bride and while planning my wedding my fiance and I realized we would not be able to afford to invite the people closest to us so we decided to wait and save until we could. We came across a wedding giveaway contest. We entered and to our surprise were selected and the contest is currently going on. We have decided if we win to donate what we have saved up so far for our weddding which is $3K to a charity. We wanted to pay it forward. We are the only DFW couple in the contest and can not get the media/radio stations to air our story, even though we would like to donate our wedding fund of $3K to a charity if we do win. There is a Houston and San Antonio couple that are all over the media. Do any DFW brides have any ideas on how to gain exposure?
