hi, i personally manage my own hosting company with 3500+ website hosted on my server.
and, i also have good experience with softaculous auto apps installer.
and, during the support period, i have done installation of many CMS and ERPS.
so, i think i would help you regarding it.
but, before moving for this project, let me know the following:
1: what exactly do you require to be done(list configurations)
2: how much disk space do you have.
3: do you require installation to be done on an subdomain?
4: after installation, are you looking for any extra support?
