Powerful server for 10 WordPress sites?

[Tilsun]

I will be doing annual billing so need a reliable provider. (have bad experiences in the past)
I need about 500GBs ssd disk, 10tbs bw, and a fair share of memory and CPU.
I currently have 10 WordPress sites to host, average daily traffic is around 10k-15k.
budget $100-120/month
What are your views on hostingsource.com web hosting provider?
Where can I read customer hosting reviews about them?

As an alternative, can recommend Regvps.com solutions. Their pricing is also extremely fair, especially when considering their reliability, service and support. With hardware virtualization, this server will be strictly isolated from other similar servers, provided with absolute information security, while still using the same set of hardware by different kernels, such as video cards, network cards, a variety of disks, and others.

Powerful servers are available from legionbox.com and sunucun.com.tr.
Very well executed hosting companies. If you are technical, they can help, if you are not technical, they can help!
