I've used papiroffly for years now to create many of our online advertising campaigns as well have helped us with customer support via chats/IMs etc.. The staff is always helpful if you need anything at anytime during their business day (as long it's not after 5pm). We had some issues recently where we would lose images when using PDF files but they were able get them back up quickly once notified by email or phone call that this was happening so no problems there other than what happens anywyaere anyways :).
