I may get trounced for suggesting this but I would say go for it - whole hog!
I am a programmer by trade (OK - a bit more than that - been doing it professionally for 30 years) but have always loved photography and videography (had a video camera for home stuff in the early 80's, had super 8 movie cameras since the late 60's and have been a serious semi-pro photographer since age 6).
I re-entered the world of video about three years ago and got serious about it about two years ago. Since then I have been reading, going to shows & user groups, viewing training materials, shooting, editing and generally playing around with this as much as possible - and at this point I am ready to propose a digital media center to my company (over 3000 employees in over 20 countries). I got to this point by doing small video presentations - they started more as slideshows with narration and music and have progressed through several compnaywide pieces and now to the point where I was asked to interview the president and CEO and create a video for our Diversity Steering Committee (on which I also sit). I was told the other day by my CTO that "my videos have enormous credibility with upper management" (kinda makes you feel good).
I have very little training in this - I did a six month photography tutelage over 30 years ago with Ludolph Burkhardt (the same guy who taught Frank Lee) - but other than that just reading, practice and determination have been my schoolmasters. I have become the unofficial "go to" guy for all things photographic and media in my company. I figure that if I can do this (with my small modicum of talent) then anyone can - All it takes is time, learning, practice and the determination that this is what you'd like to happen.
Just a final note, your company should be made aware of the costs of creating such a position - I have done some research and figure you can do a small, start-up department for around $50,000 (yes, that's fifty thousand), which would include a decent camera, a backup camera, tripod & head, basic lighting and sound, two decent computers (not stellar-just ok) and a reasonable software setup (NLE, audio tools, video tools, RF music package, RF video and still collateral). Considering my company paid a "professional" production company more than that for a horrible five minute video they had me redo for a senior management meeting (so bad I couldn't even salvage 30 seconds of it) they will be getting a bargain.
I wish you all the luck I can - Lemme know how things progress.
