Aaron, if I may suggest something, you could probably resort to an external rendering company to "test the waters". Try it on a project you think will benefit from it. There are freelancers that do renders for pretty cheap, but of course the general tendency is for practices to have it in-house.
Learning Viz can be time consuming, because at first, you will only be able to produce "passable" renders, but in a few months, with practice, you can start producing great quality stuff. Good luck!
