How much would be the hosting cost per month to host an event ticket selling site (like eventbrite.com)?

[Social Net]

I do not have much idea how much traffic this site would get. A guess might be 10000 users per month. I just want to get a rough estimate how much I have to pay for hosting the site.

Amazon Cloud web service seems expensive. Any suggestion regarding scalable web hosting service is highly appreciated. Thanks for you time.

Yea just data caching on AWS is pretty cheap but their complete site hosting is obscenely expensive, assume both for traffic and security reasons you would probably need a dedicated server. Whether is is managed for you, the speed of the PC and connection effect the cost of probably $75 to $300 a month.

Here are the options on the popular hostgator

That is really a fairly low traffic figure and realistically may be handled by a good quality shared server, something better than the run of the mill $8 a month deals. A middle ground may be a Virtual Private Server where you are allocated a portion of a server's resources, you are generally expected to hae a higher level of expertise to manage these private servers.
