haventabean, you still need to post the debts you have and the interest rate you are paying on them.
You should also look into the interest rates you are likely to pay for a CU or a bank loan.
Generally speaking, it makes sense to pay off credit cards as the interest on them is high compared to other forms of debt. But this only works if you stop spending on them.
You also need to look at your overdraft. Is it arranged? Talk to your bank and see if you can arrange an overdraft at a lower interest rate than you are currently paying. Again, this will only work if you can stay within the overdraft limit. This means you need to start working in cash.
Have you any other loans? Car loans, HP agreements for furniture, white goods, tv?
You really have to get control of your day-to-day spending if you are going to make a dent in the debts you have built up. If you can't show evidence of managing your debt to some degree, you will not be able to get a loan at a decent interest rate (one that makes taking the loan worthwhile), so it is really important that you manage to live within your means for a few months, however hard that may be.
I would suggest cancelling the wedding photographer and getting as many people as possible to take pictures with digital cameras and send them to you. You can build up a great album this way. Let's face it, you only need one photo for the mantelpiece and maybe one for the bedroom!
Get a friend to make up the flowers if you can. Buttonholes for the men and your bouqet - again it needn't cost a fortune.
I agree, receptions can be expensive and there can be no getting out of family commitments, but that is all you *have* to do, so I would try and keep all other expenditure to a minimum, like deferring the honeymoon until you have your heads above water. You can always say that the weather isn't great where you want to go, so you are waiting for a different season to have your dream holiday...
Best of luck.
