Does anyone know how much does it cost if I want to list my hosting company in this directory?

thanks.

You can get a free listing but they also have paid slots too:

I don't think you have to pay for it.

any other hosting directories like this?

YES, there are tons of directories and too many to list so it would be best to do a search on google or yahoo.com for hosting directories.
You will see plenty of results!
