A few options. ^_^ Blending grains/oat like foods with a blender will eventually piss it off (This is coming from someone who's gone through more than a few - Even commercial grade setups won't really like it). Consider asking a family member/friend if they have a kitchen aid mixer with grinder, meat grinder, or grain mill.
Consider finding a local home brew shop. Most will grind your grains for you (very cheaply), or sell preground mixes in bulk.
If you're really after it, consider buying a grain mill down the road. Without overly dry grains you'll have trouble hitting a truly small particle size, but they'll still come out well. Search for "whole grain brewing" - the beer guys have a pretty good take on what works. An actual mill might be the best bet for what you want.
I suppose I'll tread lightly here.

I still vote for checking local bakery/kitchen closings. I gave craigslist a shot for Dayton (as it's roughly in the middle), but no dice. Considering how lightweight your setups are, you could likely get away with a DIY shelving setup and save some money.
