Newbie - Sun/Light - Photoshop help

[biocal]

I went to a party and took this picture.
The owner of the party now want 200 copies of this photo, pay me 300 USD for it, but i find it SO AWFUL!
The sun ruined it all. I tryed to do my best in Lightroom, but i cant do it any better.

What can i do? can you help me?
