Looking for server(s) to host Microsoft Exchange 2013

Hi,

We are looking for a server or servers... at a datacenter that can host our email for our users. Typically, we have around 60 users that need around 100GB email box space. Yupe, they do a lot of heavy adobe Illustrator and Photoshop files. Are there any recommendation host/datacenter that I can use at a fair price? So currently we have these licenses in house.

1. Microsoft Server 2012 R2 Datacenter
2. Microsoft Server 2012 R2 Standard
3. VMware ESXi 5.5
4. Microsoft Exchange 2013 license
5. Microsoft Lync 2013 license
6. Microsoft SQL server 2012

What I am looking for is a solution to host our email exchange server and possible MS Lync 2013 in the future. We typically will use VMware ESXi 5.5 to generate VMs that will host our servers :). So...Will 1 dedicated server with E3 series, 10TB bandwidth, 4TB regular none SSD hdd do the job?

Are there any hosts out there that currently have any great offer towards this request?

Looking forward for your input. Thanks, TZ.
