iMac 2011 installation of OS Lion

Project Title: iMac 2011 installation of OS Lion Last night, I deleted my hard drive to clear the computer for sale, but now I seem to have lost access to the operating system and running from safe mode and Internet mode. I’m stuck in the iOS utilities loop and I’ve tried changing dates etc as instructed online. Need a very good Mac OS knowledgeable person. I don’t have a boot up usb or disk. PLEASE DON’T MESSAGE ME IF YOU DON’T KNOW WHAT I’VE WRITTEN. Requirements: - I am looking for someone to assist me with the installation of OS Lion on my iMac 2011, as I do not have the installation disk. - The freelancer should have experience with installing operating systems on Apple devices. - The freelancer should have knowledge of the iMac 2011 model and its compatibility with OS Lion. Skills and Experience: - Experience in installing operating systems on Apple devices, specifically OS Lion. - Knowledge of iMac 2011 model and its compatibility with OS Lion. - Ability to troubleshoot and resolve any issues that may arise during the installation process. - Familiarity with Apple IDs and the App Store is not required since the client does not have access to them. - Attention to detail and ability to ensure that the client's important data is properly backed up before proceeding with the installation.
