Okay, my dad's in interior decorator and after fighting it for years I am going to work for him and then take over the family business, hopefully with a larger scope. I've gotten a few painting projects under my belt, from redoing the dressing rooms in a clothing store to doing an entire store as a jungle with awesome walls and a painted waterfall and huge fabric flowers "growing" out of the wall....
As for the salon, a new big thing is to keep wood floors and PAINT them. If you get the right sealant they don't get scraped up. If you just buffed them down you could paint them a complementary shade to the place. Or go with tile because carpet ain't gonna do it in a salon, it looks cheap in my opinion. Is the look more modern with black and bright/baby pink and silver, or more muted/earthy with dusty pink and silver? You could always paint each wall a slightly different shade of pink and use the black and silver as accents on the wall, either just splashes of color for a more modern look, or stencil poetry or pictures onto the wall for a more structured feel. Good luck, we wanna see pictures when it's done!
