If you don’t have the budget to invest in a fully dedicated server then you can look into getting a semi dedicated server, this is practically the same but you will share a server with a much smaller number then if you were to go for a shared hosting company.  Semi-dedicated servers has the advantages of having a much larger disk space and bandwidth allowance every month which makes semi-dedicated servers very popular.

Many companies that are starting out would rather use a semi dedicated server then shared hosting as they get more privacy and tend to have a faster upload speed as the server has to deal with less clients.  The customer support you receive should be a lot quicker and more efficient as they have to deal with fewer clients so can identify the error quicker and talk on a one to one basis.

The downside to this is the fact they cost more, however someone with good technical knowledge will be able to have more control of how their site runs and can potentially solve any problems you may encounter as you get root access to your server.

You have the ability to make some extra money by renting little amounts of space to other clients and charging them a set fee per month which will help pay for the cost of the server.  If you are planning on renting a semi dedicated server, be sure to look into the company’s history to guarantee that you get the full potential out of your website.  Read up on their past users experiences to see how they got on and if they ever came across any errors or limitations.  By doing this, it will save you both time and money in the long run if you had to transfer hosts because you found a better or cheaper host.
