Uyuni (https://uyuni-project.org), SUSE fork of Spacewalk and Upstream of SUSE Manager. But CentOS 6 will be a problem because it's EOL. I suggest to setup Uyuni, attach all Systems which are not yet EOL and take care about the EOL Systems via Ansible or whatever else you prefer and as soon they are running an up to date OS attach them to Uyuni as well.

If you're not capable of hosting the solution yourself, there are solutions that have per-agent models that will cost you much less than SchoolDude, all while being substantially more feature rich. osTicket and FreshService are both great examples. A cloud hosted instance of osTicket is only $9/agent/month. FreshService is a more polished solution, but costs more at $19/agent/month. Source: about 3 years ago
