Where can I find a company that provides sys-admin/server management on-demand? I don't mean those consulting/tech companies that wants to get you under a contract, but the ones that could just accept the task and bill you by the hour.
Or a web site where you can post a job and get instant responses? I don't mean Odesk kind but more specific to good sys-admins.
My problem is that you can't hire someone and expect him to be a pro about every aspect of Linux, so sometimes we need an LDAP guy, sometimes we need Plesk person etc.
I'd be glad if you just post the websites you know, this may be helpful to everyone.
