I do this in my town in Ohio in probably the poorest county here. I will say that I don't get a TON of business because of that, BUT there is definitely a need for freelance IT work. As for not doing Apple products, many Apple devices will need to be shipped back to Apple for repairs because either it's extremely frustrating messing with Apple hardware, or B, if you yourself work on the hardware, it can void their warranty since Apple's a stickler for that kind of thing. It's much better if Apple users send it back for them to repair it than you. If it's something software-wise like a reformat or an OS upgrade, you can do that yourself easily. Otherwise, good luck. Hopefully you live in a more populated and wealthier part of the country than I do. Cheers!
