Improved limitation of DB-queries per hour by hosting company

I’ve a project with a hosting company, which has a limitation of 75000 queries per hour. With a WordPress, and about 100 queries per page, that means that the site crashes if you reach the 750 page views per hour!
And if you are as admin work on the site with data entry, that maximum is reached within 10 minutes. Removing plugins and replacing the theme works somewhat and gives about 30 minutes before it crashes again.

And guess what. I found this plugin! When I’m careful it doesn’t reach the limit in a hour and there is still 1500 page views per hour and nothing is crashing now. Great plugin. Remove that face of the guy and charge money for it. It’s worth something!
