Complete office listing website

I have a property listing website being built now that is nearing completion (developed in AJAX - so I'm told). However, I am having difficulty with the coder's product quality and attention to detail. While relatively functional, the site is sloppy and needs attention. I need a coder to step in through completion and to continue to make modifications as we move through beta testing. If interested, please reach out to me and I'll share the site details. Thank you.
