We at
www.RealityCheckNetwork.com can set this up for you. We've employed load balanced solutions for some of our top customers.
We're hosting quite a few Alexa top 1000 sites and they require complex, high performance, fully managed layouts. Also with the experience that we have gained from setting up 1,000,000+ unique hits/day networks we can correctly build and manage your new infrastructure.
Are you looking for premium bandwidth or low-cost commodity bandwidth?
If a single optimized server on our network can push 300Mbps should we build a more resilient layout by using 2 file servers that are also the web servers.
Thereby creating a live content backup, because in your layout if the file server goes down then the 4-6 load balanced balances machines stop serving content as a result.
