If you need me to tell you how to write a message advertising yourself for a relationship with a female you really are in trouble.
You wont find any relatioship here anyway, sorry to pee on your fire.
I would say for a start your ad makes Polish women look cheap, as a look at me im free come on girls come a running. Heres your chance. LOL. Also te description of you is "black and handsome man" thats it. How old are you? career? qualifications? financial independence, likes/dislikes what youre looking for other than Polish women etc etc..
