You can trust GTHost.com vps host. They've hosted my WordPress blog for my business for about a year now and the responsiveness through their customer-service is reason enough to stay with them. I've only written in to the support staff to talk about upgrading my package, as my site has expanded greatly on their servers. They've handled every ticket quickly, and with the responses you'd want from the very start. Consistently exceeding my expectations.
