as has been said a few times before, the website for your competition and your plan for the competition have a few things you need to fix. here's a few things that i personally noticed:
1) put the information on a separate page: as of right now you have the event information all on your home page, which isn't really a big deal, but it would be much better if it was on its own page. as interesting as information about you is, it would be much better if all the competition information was on its own page. a small thing, but doing it makes you look more professional and organized. you can take the denver competition's webpage as an example:

2) allot more time for the competition: you have 5 events and have allotted 4 hours. i'm not sure how long you have the room reserved for, but you don't want to run into any problems there. especially since this is your first time hosting a competition, there is a good chance that things will run a bit behind schedule. so allot a bit more time to include things like registration, lunch, awards, and leeway in general. i'd personally suggest 9-3 or 8:30-2:30 if possible, since the competitions i've seen usually follow that general trend. it's always better to be ahead of schedule than behind schedule, so keep that in mind.
3) put up a schedule on your website: you should have some type of tentative schedule up on your site. if you look at the denver competition website (just using it as an example because it's the most recent competition i've been to), the schedule is detailed: having something like this will both help you be more organized and give others valuable information about your contest.
4) put up some pictures of the venue: if you've ever tried driving to a place in an area that you're not familiar with, you know that it's very helpful to have some type of picture of how the building looks, etc. just a small thing which will help people know they're at the right place when they get there.
i think if you do those things it will greatly help you for the competition. since you haven't been to a competition before, look around at how people have scheduled for competitions in the past. this should help you to get an idea of how much time to allot and in what order, etc. good luck on your competition.
