Do you have contacts within the industry? Such a gig is hard to land without someone already in the industry recommending you, since most companies already have a guy on staff doing that shit, and 3 more as backups.
OnT though I would say the particular skillset would probably not take more than a few weeks to maybe 3 months to aquire. Then it's all about improving the speed at which you can do your work.
Of course there will always be more to learn, but if you just want to be barely good enough to do the work I'd say that's the timeframe you are looking at.
