Brandon, As well as Xen4CentOS (http://wiki.xenproject.org/wiki/Xen4CentOS and http://wiki.centos.org/HowTos/Xen/Xen4QuickStart) there are various consultants offering paid support of various kinds listed at http://www.xenproject.org/directory/directory/consulting.html Of those I know that http://xen.crc.id.au/ does CentOS (and related distros) packages and offers support (I have no particular affiliation with the xen.crc.id.au guys, and I've not used their stuff myself).
