Assumptions you can change

Self-hosting Uptime Kuma usually means one small container and a database. Hours are for one engineer; the server cost is a typical cloud VPS with backups and grows with the number of people using it.

Not included: paid editions or features of Uptime Kuma (see What's free?), large data migrations, and compliance work. All amounts in US dollars at list price; your negotiated price may differ.
