There is no guild for the companies that produce VFX work. VFX studios do the work as work-for-hire, so if a film does poorly they don't loose money, but they never ever get any of the profits if a movies does do well. At the most simplified level - it's a loosing business model. There's a very small set of "consumers" and there are more producers (vfx shops). The bid amount for work that is awarded is a tightly guarded secret (this hurts transparency). Regardless, at a coarse level if tax subsidies (in Canada or the UK for example) allow your competition to under bid you by 20 million on a 60 million dollar set of work where your normal bid is for profit margin of 3% you are screwed. VFX today is labor intensive. There is still a great deal of creative specialty skills involved, but outside of vfx they don't even quite realize how easy or hard an effect is to create and thus they view outsourcing of all work as a "sure and natural thing" This year Life of Pi won the vfx oscar, and the work was done by a company in LA that just went bankrupt (Sigh, it hurts to think about Rhythm and Hues). If you watched the award show, just as the people accepting the award were about to mention R&H they were played off the stage. Film producers do _not_ want to even acknowledge how the industry works :). As a long term career choice you do _not_ want to work in vfx. The people who work in VFX are the funniest, most passionate, and creative sorts I've ever worked with, but it's an industry that is going through "change" (as in, disappearing).
