Need a scalable Scrapy Cloud subscription

Hi there,

I am looking for a scalable Scrapy cloud subscription for my firm. 

I understand that it is $9/per unit. However, I do not want to limit myself to x units per month.

I need an option where I can start as many jobs as I want, and then pay accordingly. 

This can either be postpaid or charged to my credit card as soon as I add an extra unit. Mode of payment doesn't matter.

I just don't want the api telling me something like: "You have reached maximum allowed units"

Do you think it is possible?

Regards,

Mohsin
