Simple Wordpress Mobile Menu & Footer changes

Hi, I am looking to make changes to the mobile menu on a website that I am working on. The menu options on the theme are very limited, and there is a strange "block" in the header that I need to remove. I also need to remove an empty space below the footer before the first row of content begins. In the footer, I need to have the footer items "stacked" instead of shown in a row of 3. I also need the copyright sub-footer text changed (no options in theme options to do this). This is a pretty simple ask. Removing a block, a blank space and formatting the footer for mobile should be approx 1.5 - 2 hours of total work. Tasks: 1. Remove black block in header 2. Make logo larger once mobile menu expands 3. Remove blank space below header 4. Fix footer formatting (stack vs columns) & update copyright text (I will provide new text). I will provide tempt FTP access as well as Temp WP access. I will not provide CPanel access as this hosting is linux and there is no Cpanel. I need this task completed within 24 hours. Do not bid on this project unless you are able to begin immediately. I will scan and check all PHP and major WP files for injections, malware, virus prior to releasing milestone - so do not think this is an opportunity to infect an active WP install. Thanks guys
