You should always be on the lookout for additional events to produce.
Be careful to not allow your events to be a burden on your prospects. This is often the case when you produce a charitable event where the attendees might feel pressured to contribute to your cause. You never want to be a burden on your targets. If you are asking for contributions, you should be focusing on your vendors - not your clients or prospects.
There is more information about events in the tutorial, "What events do you plan to produce?"
