I suggest that McAusland and his people at Outland come to San Diego Comic-Con JULY 8–12, 2015. It has much potential for your companies. Beyond just hosting a booth you can be on all kinds of panels and if you have any video/animation you can show it there. There is a giant gaming room too. I don't know how much The Con Org will help cover expenses but they likely will at least give you and your people free 5 day passes. Thats huge cause tickets sell out in a day. The SDCC Org might help with your room. If you're going to book a hotel room sooner is better. Rooms within 10 miles of the convention center are in high demand. Rooms and houses are on airbnb and similar sites. Worst case get on couchsurfing.org and hospitalityclub.org Flights into Los Angeles and Orange County CA are likely cheaper then to San Diego.
Also the SD Con Org puts on WonderCon Anaheim April 3-5, 2015. Its a smaller version of SDCC 1.5 hours north of SD in Orange County near Disneyland. Its close to Orange County John Wayne airport and 45 minutes south of Los Angeles LAX airport. Plus these are all in the ME universe since you set it near LA! WonderCon has huge potential for ME. Tickets are much more available for Wondercon. For the people that don't know-today's comic-cons encompass movies, animation, TV, all types of games, books, costumes, toys etc. Sci fi and horror genres are huge SDCC and WonderCon comic cons.
I live in San Diego and can help as much as I can.
