Hi hesham373,
Welcome to the WHD forums

Although Ive never heard of the company and I have not checked their site out, I did do a quick whois lookup.
The domain is very new:
Creation Date: 06-mar-2004
I would definitely urge you to follow these guidelines and at least contact them with some pre-sales questions.

Depending on your site and needs you might want to look for a more established host thats been around a little longer.
Either way, best of luck.
