CMS implementarion for a static website

I am working on a website, which I have uploaded here for you to check: [login to view URL] as you will see is currently static. I need this website to be handled by a CMS. I have this CMS: [login to view URL] user: admin password: admin, which is how I would like the CMS to look and work. However the coder that did this no longer works for me, and I have been told several times that his code is very messy. So, I can provide you with all the files and DB for this demo, but if you feel more comfortable using a CMS framework you are familiar with, I have no problem, as long as you can make it look like mine and have the same functionallity. This the first of 3 similar projects I have, so if your work is good and you offer me a good price and timeframe, I will definitely give you the next 2. This first project is rather urgent as I mentioned. Kind regards, Ricardo
