Do you know of 40-50% converting squeeze page designs?

Hi,

do you know of any squeeze page designs which convert very high like 40-50% (depending on traffic)?

I tried to search on Google but didnt find any.

Do you know where to get some good ones for free?

I have some thoughts on what I use that gets over 60% all day long here:
