Hosting is a huge business. Everyone needs hosting, and if they don’t need it now, they will need it in the future. In theory, you could have hundreds of clients for your reseller business.
It’s always prudent to start small, and with reseller hosting, there should be no problem starting out small… In fact, there are hosting reseller plans where you can start out with as low as a budget as under $20… However, if you’re already having several dozens customers, it may be time to look into the future of your hosting business.
Once you accumulate enough customers and learn the ropes, it may be worth your while to go dedicated. You could rent a dedicated server either from your existing host, or from a different host. Shop around, dedicated servers plans vary greatly. You may continue with the existing support system provided by your current host, or you may look into hiring your own admin to run your server. With a dedicated server, your profit margin becomes significantly higher and you have more control over the kind of services and features you can offer your customers.
