the first place to start is in taking an online course which will make you a certified wedding planner. most of those are about 1000 dollars or so. the best ones will offer you an apprenticeship with a planning business so you can get some hands on experience because wedding planning is more involved than just picking out gowns and venues, flowers and food.
you much have knowledge of legal matters such as contracts, environment issues, local marriage laws as well as knowing how to find marriage law information in other countries and how to find help for people needing immigrant or fiance visas.
you also need some expertise on various traditions of various people groups and religions as well as knowlegde of how to use your computer to find out everything from what various colors mean to how to do a jump the broom ceremony or celtic handfasting.
an ability to offer people family counseling and a total understanding of proper wedding etiquette is also needed as you will have many situations that come up and your brides will turn to you for answers.
knowledge of insurance matters and liabilities are also required as many venues require their brides to have insurance of their own. so the courses which include these things are the best ones.
once you have completed the courses you can either get some experience by working for someone in the wedding business or start out on your own. you will need to have money to spend to advertise in local wedding guide magazines and your local yellow pages, have a website, and spend many hours networking with other vendors so that you become known. it is time consuming and expensive and you should not expect to make a profit the first couple of years. you only make about 10% of the overall wedding costs so the average is about 1500 to 2500 per wedding for what takes the greater part of a year to plan and takes tons of hours. if you become properly connected with other vendors, you may be able to work a recipricol agreement where they give you a percentage for anyone you recommend to them, which helps to boost income.
it's a great business but expect to really have to work hard. once you get a wedding, you are the first to arrive and the very last to leave every reception so the hours are long and tiring.
