For a young couple getting married with not much financial help from family how much would a wedding cost? At the least?

It depends what you have in mind, and what things you are willing to do yourself. Dinner is the biggest cost. If you can find ways around that, just a cake reception, or only very close family invited to the dinner, a buffet bc they are a bit cheaper. If your able to talk prices down thats also a plus. Most times people are willing to go down. Instead of ordering things at a chain store, shop at independantly owned ones, they are more willing to help you out.
