The second you know that you are going to be throwing a seminar, there are some things that need to be done. First and foremost, establish some goals. Think through what you want to communicate through your seminar and what kind of audience you hope to attract.
With this in mind, set a date that will be most optimal for the largest amount of your audience. Be sure to have a backup date just in case your first choice is unavailable.
When you have your goals figured out, you can begin thinking about costs. Create a profit goal and decide how you intend to get that profit. You can then start setting ticket prices by looking at comparable events and filling in any holes with your best guesses.
Now you can start finding the meat of your event. Research the venues, vendors, and visitors that will elevate your event. Make sure the space you choose can accommodate your group and has the infrastructure needed to host your event. The venue might also have preferred vendors, so make sure they can serve your group as well. The Business Expo center offers multiple venues under one roof.
From there, you can find speakers and sponsors who will make your seminar attractive to the audience. Make sure these people are on-brand for your event and can speak intelligently on the topics being covered.
