There are a few basic elements to promoting a concert of which you need to consider:
1. Venue: You need to find a good venue to throw your show at.
-Factors
*Costs: Venue Rent, Security Guards, Lights/Sound. Each venues are vastly different. Contact specific venues for their rates.
2. Tickets: Platforms to sell your tickets on (i.e. Ticketmaster, ElectroStub), Hard tickets via mail, or through head shops, music shops, etc. Also consider electronic ticket sales.
3. Enough people that will buy your show's ticket. You need to make money off this shit.
4. Headliners: You need to have an artist/dj come through that people will pay money for, and that is also within your price range. I heard Dillon Francis was going for as low as 2G's last winter (this could be different now that he's blown up quite a bit more), or any other bands/dj's/hiphop acts you know around your area that are good and can bring people out. Or yourself if you want to promote and get your name out there and nothing else is going on in your town, headline the shit yourself.
5. Your Break-Even point. How many tickets do you have to sell in order to not lose cash? Allocate all your costs and revenues. Match them to the value of your operating income. Look up "Managerial Accounting" on the internet for more details. It's not that hard, just a little intimidating because of the name.
6. Ticket Presale, OnSale, Night of Show Prices.
-Presale: You want to have this date be a couple of weeks before your OnSale, and typically on a Thursday (this is when people have time to check the internet, and when students are all in school so they can talk about it when announced). For a bigger show like say Porter Robinson I would start with 15$. I would try to reach break-even through presale so you can feel secure going into your onsale date.
-OnSale: Depending on the show which you are trying to sell, You want to have this last ranging from 6 months (for shows like EDC) and about a month and a half-to 3 weeks for local shows. This should be about 5$ more than your onsale ticket.
-Night of Show Price: This should always be 5$-10$ more than your Onsale ticket. Some people even crank it up to 20-40$ more than Onsale. People who show up to the venue with a fat ass line outside will drop that kind of cash to see a show.
7. Marketing: Make sure that your target audience knows your show is coming up.
-Facebook ads
-Facebook Event
-Twitter
-Radio Ads
-Banner Ads on blogs
-Giveaways on Radio, Facebook, Twitter (run through headliner's or your promo company's twitter account), Blogs (For Electronic shows Gotta Dance Dirty, Thissongissick-although they never fucking respond to emails, its fucking pathetic. GDD is dope tho.)
-Anywhere you think your target audience member will look.
Thats all I can remember for now. But thats the basic outline of the shit you have to worry about if you wanna throw any kind of show.
