I am currently looking for a new host for my site
QuoteWorld.org. Right now I am hosted on CWI Hosting and am constantly getting suspended for "using excessive system resources."

As I've read in past posts, this seems to be a common problem.
What I need is about 20GB transfer a month, but only need 20 MB in space. The biggest concern is with the processor power I will be allowed to consume. I run several search scripts with PHP through a hefty MySQL database. I also have a SubscribeMe Lite mailing list with about 10,000 subscribers currently.
CWI constantly complains that these things use up too much system power, and based on past host responses, there is some truth to this, but obviously not the extent that CQI has taken it.
I need a host that will work with me and provide reliable support, which CWI has not been able to do. I know a shared host can handle my needs, it's just a question of whether or not the customer service is willing to make the initial effort.
If anyone has any suggestions, please let me know. I am tired of my visitors frequently being greeted by a "FORBIDDEN: This account has been suspended" message. All I need is a reliable server with top-notch customer support.
