The economics are pretty straightforward: What do you need to earn per day to make a living, including overhead? And how many widgets can you fix in a day? Here you are in the sticks. Let's say you need to make $1000 a month to cover your shop and $3000 a month to cover your life and family. You need to make a thousand a week or $200 a day or $25 an hour. Can you fix hair clippers in half an hour? Can you charge someone $12.50 to do it? A bitchin' $75 Wahl, maybe. A $20 Norelco, probably not. I dunno if the iPhone battery/screen repair shops have sprouted like mushrooms where you are but around here, there are plenty of people willing to do it for less than Apple. But then, Apple probably pays $80/sf for retail around here. We needed our Kitchenaid rebuilt. It cost $70. But then, it's a $300 kitchenaid. Amazon gives me 110 results for "stand mixers" under $70.
