I was suggested with MicroVps.com. They are only VPS provider. I'm looking to the suggestions how can I check them? Which steps can be done?

What do you mean check them?

Ask lots of presales questions. Better to get the web site hosted with them and check.

Think of ServerPoint.com VPS solutions. They have to be better in terms of the amount of bandwidth? CPU and RAM they offer to their clients.
They are definitely better in these ways.
