I'm taking over a friends computer repair shop for a year while he's travelling around the world with his fiancée. If I know these people at all they'll sit down on a couch in march and get up from said couch late february next year but this is not important.
I'm not very familiar with the books yet, but it's 'bout a 100k p.a. turnover with 50k in expenses. Customers come ~50% through website, the rest referral and location. He has a bookmaker who does the absolute basics and a freelance mechatronics guy who does chip replacement and the like. Business seems surprisingly stable at 8k turnover a month with little variation.
I would not be taking this up as a job. I'd have to ritually suicide myself somewhere around mid summer if I did. I want to treat this like a game. (This is not what I told him).
Obvious growth potential: get more customers, outsource more work to freelance IT people who can hold a soldering iron. 300ft² store space in a decent shopping area, largely unused. Website: pretty good, maybe SEO, which is still a thing I'm told. Reading recommendations, online resources etc very much appreciated.
