Re-edit existing website - think Created by Joomla

My website (the domain name is shown at the left hand side of the hosting CPanel, see attach jpg) should be created using Joomla if I'm not wrong The website might have been restricted and password control by the web programmer, therefore there might be a chance that you and I are not able to do the changes. For the website, there is a control panel for me to login and edit the webpage. see attach pdf By the way, the top left hand side text "ADVANCED MENU Expert controls here" are not clickable. I have no idea whether it can be clickable or not. It could be that it is clickable but just that the web programer set it and doesn't allow me to do that. In the hosting CPanel, i'm not able to see the backup & restore icon. I believe that all Hosting CPanel should allow people to do backup for their website. See attach jpg. You need to show me where and how to edit: 1) Top Banner( i suppose it should be a banner). It has a personal photo on the right hand side. On the left hand side of the photo will be the contact number, name, .... On the left have side shows domain name So you need to change the banner background, the photo, contact number and domain name. 2) Change all the emails address to one email address only. There are a few emails address inside/hidden. 3) Change the Name 4) Change the contact number 5) Change the domain name 6) Change the photo So for all the above 6 points, you need to make all the changes and upload exactly the whole website onto your server. I need to confirm all can be edited and another person can have a website for himself/herself. Meaning, by changing all the above it becomes another person personal website. 7) Lastly, you need to show me how to backup and migrate the whole website from one hosting to another hosting (there is a possibility that i might change hosting company) Please kindly remember that all the above 7 points must be done and show it to me within 10 days. Once I awarded you the project, i will let you have the link to both control panel and the 10 days start now. You just need to migrate and upload into your server/hosting and show me the changes. I need to confirm that you're able to do the changes completely. If it is not done within 10 days there will be no payment to you. So please estimate yourself whether you're able to do it. NOTE: It is advisable that you back up and upload the complete website to your server or hosting because i do not guarantee that you are still able to access the control panel for the whole 10 days period. Anyway, i believe that it is much easier to do it on your server/hosting and also end of the day you need to show it on your server/hosting.
