CMS/Website Modification

READ CAREFULLY - I DON'T WANT A GENERIC BID - PLEASE PUT 'I HAVE READ YOUR REMIT' AT THE BEGINING OF YOUR BID OR IT WILL NOT BE READ We currently have a website [login to view URL] which has a custom CMS. This custom CMS isn't as flexible as I would like and it needs some modificiation or replacement. This is what I want to be able to do that I can't currently do. Remove the pop up competition on internal pages but then have the capacity of adding it again in the future through CMS. Have the homepage on the CMS as at the moment I can't edit it at all. Have the capacity to include videos on pages Be totally W3C compliant Be able to use the image gallery There seem to be errors with some of the fonts on the pages Have additional anayltics placed on pages There are approx 157 pages to my website so please bear this in mind Have all the relevant social media buttons on the site and working Please look at all the requirements and at the site, think carefully if you can deliver all of these and then tell me a sensible timeframe and a sensible bid. Good luck.
