There is something that a lot of people looking at businesses like this fail to realize. Something like this probably doesn't scale. You can get reasonably Wealthy opening a small specialized shop just yourself selling to just a small niche of customers. However, this business doesn't scale: You will never be worth ten million dollars opening a business like this. If you are fine with being a one or maybe two people working in a shop and earning a good income but working 40 hours a week supporting your customers, yeah, it's worth a shot to open the business. You will never be as large as Google and so you'll never be worth billions of dollars but might be good business.
Unfortunately I had to use might there and not Will. I do not know for sure if this is a good business. I would like to say I would recognize such a business if it was near me, but I don't know. I can do this myself. I don't know if you can make enough value that it's worth me paying. If it takes you three hours to flash a router, I can do that myself. And even if it takes me six hours, Three hours of your time at a reasonable wage is more than I could afford.
