If you have access to a lift, I would DIY using degreaser, brushes, and towels. A few years ago I sold my E39 M5 I had owned for 14 years on BaT, and in prep for the sale I did a full undercarriage cleaning. The car had 66k miles on it, but it was rarely ever driven in rain, never in snow, but the accumulation of dirt over 66k miles still took a couple of hours on the lift to clean. I wore a Tyvek suit and goggles. Here's a couple of pic links (didn't embed them since they are so large and this forum isn't resizing them):
