Hello webmasters:
I'm new on this site. Looks informative, though too much info to digest

I'd appreciate if you could share your
personal experiences about hosting providers
in the US.
I'm updating web site for a small real estate business in Washington State. Their front page could get up to 100 hits per day. I used IX Web Hosting before but I'm not satisfied with the MySQL on their servers -- it's not fast enough.
I need to find a web hosting provider according to the following:
(1) Reliable, fast server response (esp. database engine);
(2) Trustworthy -- some personal info from customers will be temporarily stored on the server before it's retrieved by site Admins. In particular, tenancy application with names, addresses, SSN;
(3) Located in US only (demand from the owner);
(4) Support for PHP + MySQL;
(5) Support for multiple domains (which we own already)
Any suggestions will be greatly appreciated.
