Hold Your Own Event in Your Own Venue
One perspective is for you to hold your own event in the place you have. By owning the venue, you are one step ahead of other event holders. Having gathered some invaluable experience, you can implement your ideas in the event.
You don't need to think of holding any specific event. Based on your venue, research the market and see which types of events are booming. One reasonable way to choose the type of event you intend to hold is to evaluate its business market. For example, the food industry is booming. Hold an event whose audiences are those who work in supplying foods.
To hold your own event, in addition to the research you have done, you need to pay attention to the market's future and potentials as well. For example, you see that most organizations and companies are looking for where and how to hold their events. In such circumstances, the best thing you can do is to organize an event regarding "how to hold an event". Not only is this event relevant to event holders but also peripheral businesses such as booth design, food distribution, print and publication, etc. can be your event's audiences.
Another method is to hold an event similar to a popular event held every year. Since the venue belongs to you, certainly you are capable of pulling it off better than any other event organizer who rents a venue.
