How Much Help Do You Have?
The DIY option is great for those who have a lot of help and support. You might have your mother, future mother-in-law, cousins, sisters and best friends ready to assist you every step of the way. If you want a smaller ceremony and don't have a lot of family or friends, you might look at whether the venue you selected can help. For example, the Chevy Chase Golf Club has wedding planners who can help you pick a location at the country club, find caterers and decide on decorations. Similar venues may offer help as well.
What Does Your Guest List Look Like?
Hosting a DIY wedding and reception is generally best when you want a more casual affair with just a handful of guests. Make sure you decide up front on how many people you want to invite. If you find that the list keeps growing and spiraling out of control, it's time to get some professional help. A wedding planner can assist you with finding invitations, addressing and mailing those invitations, working out a menu with your caterers and ensuring that you have enough seating on hand for all your guests.
How Much Money Can You Spend?
Whether you plan your big day on your own or with the help of a professional often depends on the budget you have in mind. Wedding planners can charge an hourly rate or charge one set fee based on the amount of work and help you need. If you find yourself pinching every penny to save money and bring your wedding in under your budget, you may not have enough left over to afford professional help. Working with a planner, however, may be exactly what you need to stick to your budget.

Consider all these options when deciding whether to work with a planner or have a DIY wedding.
