Hi there! I am an American-born, native English speaker and ran my own hosting company for several years. Based on my experience supporting similar issues (I have done hundreds of cpanel/DNS support cases), realistically these tasks will likely take 2-3 hours to complete in a thorough way. This includes phone time to get the ftp client set up correctly on your end. As a newcomer to freelancer, I will be glad to help with this in order to begin building a good track record.
Regards,
Adam
