Just open like 20 tabs and fill each of them with other successful tournaments and just look over the format, headings, layout, etc. until you form in your mind what makes a good event. Also use contacts to increase coverage or notify key players. Just posting on a forum about it that will get buried in a few hours will probably not be spotted by top players unless they have good management doing it for them.

Also, getting casters on board can be challenging sometimes so start that quite early. Once you get to know the casters better you can leave it until last and even just announce it on the day if you are confident they will show up. For events just starting out, you may find many casters are quite bogged down already, but look around at some of the lesser known casters and find some that you like - it can be a chance for both of you to start something good!

A prize is always great, even if it's just a community tournament you can get some prizes that have no financial value, but have sentimental value. For example, an achievement or forum signature or something like that. Also if you can set up some kind of interview with the winner it's a lot of fun and makes the player feel more like they have achieved something.

So for now look at a bunch of tournaments until you decide on a format and base for your tourney - for example you might want to host a single elimination on SC2SEA, or a group tournament on challonge, etc. Once you know what type of tournament it is and who may be playing, line up your caster, state your prize (if any) and spread the word! n_n
