Hello dragonx,
Before you start a web hosting company, consider the following:
- Will you have the time to run a company by yourself?
- Why should customers choose your services over another?
- Do you have enough hosting knowledge to provide support to your clients?
- What will make your business unique, and will not seem as "just another webhost"?
Before you start a host, make sure you'll be prepared for whatever happens, unexpected downtime, bad ratings, etc. I recommend that you draw out a business plan, and set out everything that you plan on doing.
And as always, be professional.
Cheers,
Joey Malinowski
