How to provide tech support as a sole proprietor
Technical Self-Employment Is A Fat Paycheck Waiting to Be Pocketed by Grant Barrett via "Growth Job Sector: Freelance Technical Support" on slashdot.
Mr. Barrett writes an entertaining and very informative article about how he works with small businesses to provide tech support - and makes good money in the process. A great read.
My favorite quote (regarding why one would not want to target home users):
You will no doubt encounter those legendary users who think they have a touch-screen computer, just like an ATM, or who search for "hotmail" on Yahoo every time they want to find the link to check their mail. If that last sentence seemed reasonable to you, I would encourage you to consider selling Grit subscriptions instead of finishing reading this document.
