As I can see you've about 17 bids on your proposal and average is about $56. I can offer you same PHP based solution but instead I've something better to offer you, if you pay attention and of-course it's going to be easy on your pocket.
I can build you websites based on Jekyll(runs on Ruby), which is a static site generator, it works just like WordPress, you can add as many pages or posts you want. Since it's a static site generator, it's amazingly fast and secure, it's damn easy to use and it can be hosted for free on GitHub.
So basically you can have a website for around $25-30 which will be responsive, fast, hack-proof, static yet dynamic and with free hosting.
