Custom Theme for Wordpress

Hi, I need someone to design a dental blog using the free wordpress. However, this is meant for an affiliate site, thats why the design should be for CONVERSION. think of it as landing pages, they are meant for conversion. IF you have designed anything like this before, Pls SHOW EXACT examples. i prefer someone with experience thanks and good luck rudy P.S The design must be original and unique. No free theme please. thanks
