No.
I started in tech support in '98. I worked my way from a trainee associate in Sophos's UK support team to managing a department of 30 in 5 years. I left Sophos in '06 to start my own business.
I am in a similar position to you in some respects. I started my own locally-focussed business as the tech guy. I placed an ad in the local parish newsletter for 25GBP (~40USD) for the year. That ad has paid for itself 400+ times over since then.
B2C support is tough. My demographic is adults, typically 40+. People are sometimes reticent to ask for help, especially with cheap laptops. Be approachable. Be a nice guy. Be professional. Be honest.
You'll learn about your area pretty quickly. I started out with an external hard drive and a screwdriver set. It's 90% laptops and tablets, and the repair side of my business is slow to catch on. The low purchase cost of laptops and tablets makes people less ready to commit to fixing things, instead choosing brand new. Sad, really. Apple device users tend to be more keen to get things fixed up.
Poke around on /r/computertechs[1] and start thinking about a software toolkit. Get a basic website and sign up with iFixit Pro[2]. Familiarise yourself with their store; they do good parts at fair prices. My website[3] isn't anything special (and isn't finished, either), but gives you an idea for what works around where I live.
