Well I happen to be a sole proprietor, second generation contractor started by my dad in 1946, I've owned it for 25years, back then their was no such thing as an LLC. Adam, aren't you a rancher/farmer now? that should make you a business and come with all the benefits and deductions; tools, buildings, even your rangers plus give you your ID #. I know years ago when income was plentiful my accountant always wanted me to incorporate, today not so much as corporate taxes are paid if you make money or not. I had this discussion with my lawyer when I bought my dad out and according to him product liability is near impossible to prove. The other thing to consider here is insurance, this won't be covered under a farm blanket but will need to be specific and that my friend ain't cheep. I'd say go ahead with what you are doing now, pay attention to any single account receivable over $600 in one year, if it's for someone who can deduct it then you'll get the dreaded 1099 and have to claim it, remember deductions can be played with, income should never be.
