Wedding Help

I am looking for some monetary help for my wedding. It is Sept. 20th and I am lacking about $6k. Me and my fiance have been saving and working hard to pay for the wedding but there were holes in our budget and things came up that we didn`t expect. We are trying to figure out anything that we can do, but have come up empty. We do not have credit and cannot get a loan and our families are in no position to help us. We have just under 4 weeks til the wedding and don`t know what to do. We are willing to put up our vehicles as collateral and do what we can if there is anyone out there who could help us. We have so much invested at this point and we don`t know what else to do. We are not looking for handouts, just help. We are willing to pay back anything that is loaned to us with interest!
