Joomla Site Update & Minor Fixes

Hello, I am looking for someone who is a Joomla Expert. We need our Joomla website updated the newest version, and also to make sure some of the extensions we have installed, work properly with the latest update. Website: [login to view URL] We also have a few bugs going on with the site that we need addressed as well. Here are the bug issues: 1. Menu Edits - We noticed that we are unable to make any edits to our menu, as the changes are not being saved. So any edits we make, is not taking effect. I have attached a video to help show the issue we are having, the video attached is titled: [login to view URL] 2. Schedule Section Dates - When we add an event to the schedule in the backend of the site, it will only show the month and date on the front page, vs having the name of the actual event that we are posting. Refer to attached video: [login to view URL] 3. Front Page Banners - I have added banners to the front page from the banner management section in the backend of the site. However, it looks like there should be a second page of banners in the backend, but I can not access it in order to disable the banners I no longer want to appear on the front page of the site. In addition, I am unable to select a banner and delete it. Refer to attached video: [login to view URL] 4. Twitter feeds not showing on front page in footer. Refer to the end of the attached video: [login to view URL] So if we can find someone to make these fixes, and then update the site to the newest version, that would be perfect. I have done alot of projects on here, so please provide a fair price or you will not be selected. In addition, I need this started and completed ASAP. I do not want to award this project and be told that they can start tomorrow morning. It is an urgent matter on our end so we need it addressed ASAP. Any questions, please contact me. Once the project is awarded, I will provide the admin login credentials etc. I will then require your ip address to add to our server's whitelist. Thanks! Joe
