Can I play or watch tennis with women as a professional tennis player?

I'm a tennis player and I have to go out to several countries to play tennis. There are women with revealing clothes. Can I see them without lusty eyes of course because of my work you know, some times the umpire is female and in hotel the receptionist is also female and etc but I heard the hadith that who ever see a non mahram on the day of qiyamat a rod of iron with lava put in ones eyes. So does this mean that I can't talk to any women even if it's because of my work and what is the ruling on touching or handshake without any lust. In several countries girls are open minded and if someone wins a match, he may need to shake hand with female umpire and sometime I need to practice with women, after practice we need to shake hand. So what's the ruling on this am I doing a sin? can I watch women's matches while they wear mini skirts while playing as I'm not watching them but just watching the match without any evil thoughts.
