The best place to find a carpenter to install a rolling ladder is the website of the manufacturer who sells the ladder. Usually they have a list of regional installers who are familiar with their product and have made several installations. Use the "Installer Locator" feature on the site to find a carpenter who is familiar with the ladder installation.
You may find someone who advertises in a local newspaper or at a cabinetry shop where they do custom work and installations. Often they charge a minimum fee to cover the expense of traveling so make it worthwhile for you and them and have them do more than this one job.
