There are many well established web host providers. But to ake the appropriate choice, you have to decide what exactly it is your looking for. Do I need customer service, security, etc. Or do I just need a web host thats reliable and wil give me the uptime I need. Do I need a reseller account, or would moving on to my own dedicated server be a better choice. What your looking for, what kind of hosting, and then from there, you would look to see what features, etc, the web host package comes with. But from the begining, the above mentioned is the most important step in your decision process.
