What it Takes to Start a Virus Removal Business
Don't rent office space. Here's what you do need:
Absolute Requirements: Unless you've already perfected virus removal, you're going to need a spare computer for practicing and testing (minimum Pentium-4, 256 MB Ram). I don't recommend practicing on your own computer, much less your customer's.
Strongly Recommended: A car helps significantly. A cell phone and laptop will facilitate mobility. Finally, as with any business, you need to spend money to make money. Recommended start-up cash: $500. You're also going to need cash to live off of while you build your customer base.
Your target demographic: wealthy home computer owners. Do you live around them? Are there other small-to-medium-sized businesses around?
Nice to Have: A good office space. You can easily, legally work from your own home in most areas, and I do not recommend renting office space right away.
