Create a Mobile Website

I have a small website (about 10 pages but they are all exactly the same) .... Right now, there's a mobile version for iphones but it doesn't look all that attractive. When I view the site on desktop devices and start to slowly minimize the screen width, the site does NOT conform to the smaller and smaller width. So I need some help making the website display perfectly on screens of any size. No matter how small I go, I want the site to be perfectly optimized for that size. Please let me know if you have expertise with this stuff and can make my website look amazingly professional on all screen widths!!
