Defect fixes and new feature development for VirtualCallboard.com (demo.vcallboard.com) - repost

We have a large, prioritized backlog of defects and new features that need to be developed for our web application, VirtualCallboard. Our site was written in custom PHP, so you will need to spend some time getting to know our environment. No frameworks were used for the php. Some of your work will be in-spaghetti-izing the code and making sense of old madness and using new/better constructs as you work on he code base. We need someone who is good at writing clean code and cleaning up others messes. :) We are using Bootstrap for the layout engine and Jquery for Ajax and client side interactions. You will need to have a decent command of these technologies to help take our site to the next level. You can see a demo of our application at demo.vcallboard.com. This is ongoing work, so we are putting it out for hourly bid. Please have at least 10 hours per week available to work on it. Will need to show constant and steady progress.
