After our website is launched, who maintains it?

If the client organization has at least one technical staff member, then the project manager usually chooses that individual to maintain the website going forward, or at least serve as the single point of contact when sending me requests to make updates to the website. Smaller organizations usually do not have programmers on staff, and so they ask me to maintain the website. I can perform regular backups of files and databases, make requested improvements to the website, add new features, and update the CMS system and its modules. All of this work is billed at my regular rate. The website content is the responsibility of the client, but I can always help with any technical issues.
