We use Azure and we have multiple sites we're getting that visitor count (or more, for PPC campaigns) for way less than $7/mo using Cloudflare/Azure Edge/Web Apps. This might not work for a single site, but multiple sites on a service plan we can handle way more visits per site (especially if it were static) for $2-$3/site/mo and we could auto scale if needed though that would raise that number, it would not exceed your number. Unless I'm missing something, I don't see how $7 isn't viewed as rather expensive for that visitor count.
