I'm a wedding videographer and I've seen a lot of money saving things through the years, so I've got some good info for you, but first a word about your finances.
You should definitely take immediate steps to correct your credit and debt problems. It may be equally hard to correct money problems while single as it will when married, but marriage will introduce lots of other stressful issues and you don't want the deck stacked against you. Money is the number one cause of fights in a marriage. Get as close to a debt free lifestyle as possible before marriage, and strive to stay that way after. After marriage share the bills and bank account and be accountable to each other. I recommend any of Dave Ramsey's books.
In order to pull off the following, you will have to be willing to accept help from friends and family and not have the goal of impressing wedding guests with elaborate food and drink and location. If you can do that you can have a beautiful wedding that guests will enjoy and you will grow closer to your friends and family in the process.
Use money saving strategies like the following:
- Check with local dry cleaners who specialize in wedding dress cleaning. Sometimes brides will drop off their dresses for cleaning and preserving and will never pick them up. (maybe they got divorced and didn't want it anymore) After a long time the dry cleaners may try to sell them or will donate the dresses to charity. If you ask the manager, he may be willing to let you look through the dresses and purchase one. Then just have it altered to taste. (estimated savings = $1000 - $2000)
- Ask family and friends to help make finger sandwiches and hors d'oeuvres. A wholesale club is a great place for things like meatballs and other pre made apps. (estimated savings = $1500)
- Consider an outdoor wedding at a state park or a backyard wedding so there will be no cost for a church or venue. (estimated savings = $2000)
- Ask friends and relatives to find or make things like programs, ribbons and bouquets. (estimated savings = $500)
- Pick a common color dress that most of your bridesmaids should already have, like black or white and buy a matching colored belt or sash of your choosing. Ask the groomsmen to wear dark suits or jackets and have them buy matching ties the color of the bridesmaids’ belts. If you save the bridal party money on buying a dress they will only wear once or renting a tux they will only wear for a day, they will be more likely to help with other things. (estimated savings = grateful friends)
- Get a friend who's interested in photography to take pictures with a digital camera. If they don't know how, borrow a married friends wedding album and have your friend make a note of all the poses and shots. This will give your friend a demo wedding if they ever choose to continue photography. Don't have a friend? call the local colleges' art departments and put the word out for a student photographer who will work for a small fee and give you the photos on a cd-rom. Then let family print the ones they want at walmart or some other photo shop. (estimated savings = $1500 - $4000)
- Video? Same thing, ask a friend or find a college student and borrow a home video camera. Make sure they use a tripod and set up at the back center of the ceremony. This will look very good as long as it is an outdoor wedding. It will look not so great at an indoor wedding with low light. (estimated savings = $1000)
- For the cakes, put your feelers out with friends and family for someone who loves to bake and doesn't charge a fortune. Don't be surprises if you find a little old lady who would do it for pennies per serving just because she loves to bake. ( estimated savings = I have no idea what cakes cost)
I've seen all of these ideas at weddings I've attended. There's no reason you couldn't pull them off too and have a big wedding feel for a small wedding price. Good luck.
