Most of my money comes from contract work for public utilities around the country, but I also provide remote tech support to small business and SOHO clients, mainly (but not exclusively) in the USA.

I do a fair amount of custom work for people when a loved one dies: unlocking computers, data recovery, and account recovery (Advice: keep paying their cell phone bill until you've got all their data back).

Also, personal cybersecurity for journalists, TV reporters, politicians down to the City Council level, and political candidates. TV stations: contact me for contract pricing for your entire news team.
