Hey Bernardo! Welcome to the board.
You're probably a good candidate for the "Green Tortoise" hostel in San Francisco. Google 'em. Maybe you could spend your August there while you shop and get ready. They drive buses out to the Burn and provide a few of the basics (shade, water, food). Nothing fancy; you'd still need to buy a tent and stuff.
Or stay somewhere else and fly into Reno at some point, rent a truck, drive out . . . you don't necessarily need a camp, you know. Costs & Logistics of Flying to Renoviewtopic.php?t=52826&p=770401Box truck camping tipsviewtopic.php?f=277&t=35289
Best of luck to you. Plenty of information here, and we're usually nice about questions if you look like you tried to find the answer first.
