We will still do content (page/blog posts) updates to your "self-hosted" site but we will not provide regular backups and security/maintenance.  Site maintenance would have to be audited on a per project basis as we cannot guarantee other hosts have dependable security/protection.  We will take backups whenever we do work, but keeping a site secure will have to entail a backing up solution for the client if not hosted with us - one solution would be for the client to pay for a WordPress backup plugin. Our company operates with premiere managed WordPress hosting for our client's site security and updates.
