API Limit Questions for Large Client with 100M Products

[B R]

Dear Adwords API Support,

I am evaluating creating dynamic Adwords text ads using ad customizers for a new client with 100 million products. 

On the Adwords Account Limits page, I saw that there are several limitations to this projects success. 

What is the process for getting increases for the extraordinary large client with commensurate ad spend?

Targeting limits:

5 million ad group targeting items like keywords. We will need 100 million keywords

Limits for Business Data and Feeds

5 million rows or feed items per account for dynamic ads, ad customizers, and extensions. We will need 100 million rows in the business data feed

Thanks!
