Make a design for your wedding, put it on paper, and shop around for businesses and services who can give you that design. Once you start seeing what service providers will work with your design, you can begin to sort things out by price and type of services offered.
Have some faith in other people to help you plan your wedding. Due to the fact that you are heavily invested emotionally in your wedding, this may be difficult to do because of your desire to have control over what happens. But, it is important that you trust the advice of those who may have more experience than you in certain areas of the planning and implementing the checklist.
