There is no need to take out a loan. Do not go into debt to become an event planner. There isn't any type of necessary certification required. Take an online line course and read the book How to Open and Operate a Financially Successful Wedding Consulting and Planning Businses by John N. Peragine Jr. You don't need to spend more than say $800 tops for a course, I paid less. If I were you I would skip the DJ training and stick with wedding planning and I can see how being a travel agent could help if you want to assist your brides with their honeymoons. If you want to get into something else wedding related look into floral design and event design. That will be a big help for your brides and having multiple certificates and training in these types of fields will make you stand out from the other planners as you can asssit your brides with more and therefore charge more too.
Good luck just do not go into debt it is truly not necessary for this field.
