Kiruba, if you still need a recommendation about what to look for in a hoster, I can tell that this no one here can give you a 100% comprehensive answer, as we don't know what type of sites you are going to host and what are your priorities: uptime, support, OS, requirements in terms of disc space and traffic bandwith. I think you should start with the type os OS you need, whether your site is static written in HTML or dynamic ,using ASP, in the first case go for Linux, in the second your bet is Windows. Once you've decided on that, think about your needs in terms of disc space and bandwith, scripts you're going to run on your site, whether you are going to use ane E-commerce software. For simple personal sites a shared solution will be ok, for bigger commercial sites, planning to expand - VPS or a dedicated server will do. Make your choice and limit the initial number of hosters. The next step is your decision on the type of support you prefer. You may need phone support if you find that convenient, some prefer live support, but I find the most convenient way of support to be ticket system, if properly organized like at ahosting.biz, works great!
The next question is how much uptime you really need 99,9%, 99% or 97%, again it depends on whether your site is mission critical or not.
And of course, the question of price will limit you to choosing from a few hosters. Read their reviews and ask at forums. Good luck!
