Well let me think, I would say a brush cutter would be a good money maker, go out and clear over grown fields with it. Lets see what eles, maybe a stump grinder and do stumps. You could get a breaker and do removeals of driveways and other concert. Those are the most general all around attachments. Everything eles kinda works into an over all business modle.That is hard to say without knowing your area and what you intend to do.
I'm assuming you have a bucket already, a set of fork is likely the next most usefull thing.
For myself it was the backhoe, for water lines, trenching, pulling stumps and rocks, A hoe has alot more breakout force the just the loader does.
Next was a auger, sonotubes, setting posts or building poles, planting trees.
But it is really a matter of figuring out what your area needs,

I think the highest margin work for a skid steer operator is agriculture/game fence. My father recently had some done, we got qouts from several installers and considering the mark up, I could have bought the equipment for my skid and saved money. I have been considering do this part time becuase it's so profitable. Your retired from IBM, do you live in the tripple cities?Since I bought my auger, it has become a real crowd pleaser in my neighbourhood. Setting posts is relatively easy work that many people think is more complicated than it really is.
