The one I know right now locally needing workers is this....dont know in what capacity their in need of...but you could contact them and see....
Its the large'ish fire performing platform open to fire performers, but there is fire pyrotechnics/sound/platform design and build,packing/unpacking/putting it all together playa side.
Its HARD work, I kid you not. We helped build the original platform for last yr and yr before. and actually went out on the playa a week early to set it all up.
Hard work but very rewarding, VERY VERY rewarding!
Names pinemom, but my friends call me "Piney".
