1 million pages per day is too much for Arvixe hosting, which is cheaper option for less trafficked websites.
For 30M pages per month, I would recommend a dedicated server well configured and tuned, and it would work well for this use case (even with most plugins enabled!). We also offer Enterprise Hosting, a fully managed Piwik service (contact here and mention enterprise hosting). I hope Piwik will work for you!
