Increasing quota on google elevation api

Question

I am sending from my application queries to the Google elevation api, like http://maps.googleapis.com/maps/api/elevation/json?locations=39.7391536,-104.9847034&sensor=false.
I have reached my daily quota after 2500 requests and google states in their documentation that I can buy extra quota.
However I was unable to find where I could buy this quota increase. Any idea ?

Thanks.
