Hi @slobodan
Instead of paying someone for setting up your server and maintaining your server (updates, security, support, plugins, etc.) you might be interested in the Aivie Mautic Hosting.
Our Mautic set-up and the pre-installed plugins will guarantee you a fast and hassle-free set-up, onboarding, and usage experience. Aivies goal is to provide you a Mautic with all the flexibility of open source and the user experience of a SaaS.
