Cosmetic Spa Surgery Website

I am a board certified physician who after a long weekend of negotiating has decided to construct a new wordpress site for the new office in Las Vegas. I need a template ( or theme ) that has an elegant, comforting look but has enough built in capabilities so that i could maybe put it together over the next weekend? Any advice on themes that may be appropriate for a medical office or day spa would be perfect. I would like to improve on this ( my first design for the las vegas office ) http://lasvegasurgentcare.com/ because the home page needs a bigger picture and apparently my logo is off.
