I would separate “managing your online presence” into three different jobs: keeping your business information and customer contact paths accurate, generating demand, and measuring which work becomes booked business. A company can be good at one and weak at the others.
Before signing anything, ask exactly what they will change, which accounts they need access to, who owns the website and advertising accounts, how calls and forms will be connected to booked jobs, and what you can take with you if you cancel.
I would be cautious with anyone promising rankings or packaging the website, Google profile, ads, and reporting into one fee without clearly defining the work and ownership.
