You would have to provide a whole lot more information for anyone to even make a vague guess. There is no set time or price limit that can be set for something like this.

What have you done so far to catch up?

web hosting. i don't know why i can't submit my website address in post.
but i want make a about Test For Web hosting website.
web hosting keywords. in google page 1. all is pr6 and pr7
i dont know how to catch up with they.

I guess I'm not clear on what you're asking. Are you trying to catch up to a specific PR 6 site? From what PR? Are you starting from zero, or do you have something established?

The web hosting area is extremely competitive. It's very crowded with affiliates trying to make information sites that favor the hosting company that will pay them a commission if they pass on a referral. You want to enter that market and compete with the established leaders?

Oh, and by the way, welcome to WebmasterWorld wjq3315509.

Yes, stop worrying about PR. The toolbar PR you can see is rarely updated and is not always accurate.
