If you find a friend with these qualities, wake me up.

It's fine, though I think that 'let me know' is more likely than 'wake me up'.

Ok thank you so much teacher. I meant by using 'wake me up' ( I could not find another expression that is more appropriate.), that it is hard nowadays to find a true friend, because people are becoming more and more materialistics ,so Regards,
