Having shared hosting is all well and good but if you want real control you need a dedicated server. The advantages of a dedicated server are:

• Customise it how you like - you can choose any operating system and control panel
• No sharing with everybody else - so there’s no chance of your site getting bogged down if somebody else is eating up all the CPU resources, or potential security risks from somebody else’s insecure scripts
• Administer it yourself - if you wish, you can administer the server yourself via SSH as you will have root access
• Built in redundancy - if you have a sudden surge of visitors to your site the extra resources are there to handle it without any drop in performance
• Host as many sites as you want - many control panels (cPanel included) do not have a limit on the amount of accounts which can be hosted

 The only downside to a dedicated server is the cost as this is likely to be over £100 per month for a good server from a reputable provider, however if your website is your main source of income it may well be worth that.
