I did this for about 10 years, eventually it became a full time job too - so I was working anywhere between 80-120 hours a week between my job and my business.
I’m the type that has a hard time saying no to a potential client (and their money), so I take on more than time allows…if you aren’t that kind of guy, you may be ok. People will get wind of any decent IT person around and it will grow completely organically - you’ll be surprised at how many people will call you who were referred by other clients.
I always wanted to leave the corporate world though, so eventually- about 4 months ago, I left and I couldn’t be happier with the decision. last month I billed over $10k.
I do home and small business support, build OEM computers for businesses (and gamers), and have a M$ refurbishers license - so I can refurb and sell machines on a budget. I prefer working with businesses, but I like to try to get them on a contract so they don’t have the opportunity to ask the world for nothing. (x$ a month, and I’ll give you so many hours of remote support - the most needy of my customers is getting about an hour of my time every month with very simple problems but paying about $150 a month for that - plus they buy ALL of their equipment from me for 3 businesses)
With home user stuff, I rarely visit their homes - but for a lot of very simple jobs you can make some quick money. In my small and poor town I charge $75-$100 for virus removal(an hour), $150 to replace a laptop screen (includes screen)(30 min), and reject any job I just don’t wanna do (“no, I can’t replace your screen on your ipad here’s the number for who to call” – yes I can, but I don’t want to)
Tips:
Reduce debt, like…as fast as you can. I used a snowball method. this will give you the freedom to choose to defer needing to do this long term, or even the freedom to do this solely.
Don’t kill yourself with stress or being away from home
get a license for remote support (I got a teamviewer corporate license and it pays for itself over and over).
if you want to grow: Join your chamber of commerce, be visible in your community, shake a lot of hands.
