Everyone needs an online space so you'd do well in this market. The issues will come with people who cancel their service or want to for a variety of reasons. Your rules and FAQ must be crystal clear. So they can understand what type of contract they're entering into. Also don't gouge customers by raising prices once they've signed on with you. It'll surely result in a bad rep and bad reviews for your company. Lastly, your TOS must be made clear also. People who use hosting sometimes have malicious intentions. They sell illegal products, or use their online space to launch hacking and malware attacks. If your hosting site is tagged as a haven for these people, you'll get shut down by the big boys, and larger problems could arise as well. Legal ones.
