Hi I'm looking for a windows vps 30gb space unmetered bandwidth 512ram Quad Core CPU (need high cpu for video converting) $20/month
Your budget is a bit to tight for a windows vps. Many resellers authorized to sell windows server have to pay about $19 per month for the license to Microsoft.
Guess webintellects.com would be a right company to use a Windows VPS from. They are reputable and provide dependable policy. Servers are well-supported and their VPS plan is full-featured.
If you're looking at this for just $20 (the ability to max out a CPU using x264, e.t.c) - expect to have your account shut down rapidly.
Its good that you have decided with which web hosting solution to opt. Windows VPS is a good solution all together, you can check my signature and go to the Windows VPS link and try to opt for the best of the services. I would suggest you not to keep Money as a limit for you, If you are expect the best of the services All the Best!!
