I doubt $100K is
anything like a typical profit for putting on a small time conference, i.e. one that can be done with just some additional volunteer staff to help with registration etc. A conference like that is doing well to get a few hundred attendees and even a $100-200 registration fee is probably on the high side. OK. Maybe you can get some sponsorships but that's another task to do--and vendors get a lot of requests for sponsorships. Considering all the expenses, you're probably doing a good job if you breakeven--especially for a conference with no track record and an existing attendee mailing list.
