I'm with Softlayer in Dallas...but pretty sure you don't need $x,xxx.xx monthly hosting fees...they are expensive, but worth every penny when I don't get that 2am phone call from Poser that the site isn't responding...
HostGator has received good reviews...check data center location, MAIN hubs = better response time (Chicago, Los Angeles, Dallas, Denver, Vegas, etc) Check that the host is IN THE UNITED STATES...I hosted RockCrawler for a whole month on a Canadian server cause it was cheap....and when I called, they spoke French...and after 30 days of up and down, I ditched them.
Find one, and search Google...

24/7/365 phone and live chat support is nice...I used
https://totalserversolutions.com/ to monitor IH8MUD servers before I switched to Softlayer (didn't trust my old host anymore) and they were fixing site issues at 3am with a 15minute response...again, you pay for it, but worth every penny...
