Need advice

Need to know best providers for dedicated hosting, someone who lets me sign up with fugazzi names, and super fast to quickly load tech pop ups for tons of simultaneous US traffic. I have a feeling my current setup is allowing lots of people to close page while loading.
Also if you know anything about optimizing fraudbuster for tech support I could use advice there. New to the game, things are going decently but cost per call is still huge so im optimizing everything. Using adwords display network right now tweaking things left and right.
