Hi, Im a sysadmin with huge experience, focused on LAMP and in open source deployment.
I already did many installation of owncloud and know in deep the project.
I know
I collaborate with it and implemented 2 apps (auth_saml and auth_cas) for owncloud
You can find me as a member of its git repository.
What type of service you will provide with your owncloud instance? Is a domestic instance?, or are you are planing to use it as a service for 300+ user?
Choose me if you are looking for a trusted worker. I will deploy you an owncloud instance and configured under your needs.
Also If you plan to customize the theme or make some hacks on the code, I can do it for you in other contract.
