Youtube API higher quota (form) : response time an

my team uses the Youtube API for a 2 week contest, where participants have to send a video. We want these videos to be hosted on Youtube, only for 3 or 4 weeks.

However, according to the Youtube's API Documentation and the Quota Calculator :

A video upload has a cost of approximately 1600 units.

and

Queries per day (default) : 10 000 units (max)

This means that we can not have more than 6.25 videos sent per day, which is very problematic in our case.

It is also indicated:

If you reach the quota limit, you can request additional quota on the Quotas tab in the Developer's Console.

To increase this maximum value, you can request a higher quota with this form.

We have completed this very long form (yesterday), so we have three questions:

How long does YouTube have to respond to this form and what are the delay for increasing the quota?
We have a billing account, what is the price of a quota increase over 3 or 4 weeks if it's necessary to pay ?
Do you think it is possible to contact live (phone / chat) to speed up our request?

These questions may sound silly, but it's an emergency and I have not found answers to my many searches here and in the API documentation.

Maybe some people here have already asked for a quota increase and will be able to answer those questions.

Thank you in advance for your help.

How long does YouTube have to respond to this form and what are the delay for increasing the quota?

It really depends upon the API. Some can take as long as two months others take a few weeks. It can expect it will take a while.

We have a billing account, what is the price of a quota increase over 3 or 4 weeks if it's necessary to pay ?

To my knowledge the YouTube API is a free API. To my knowledge there is no public pricing for it.

However if they contact you can work with a developer relations manager to increase your API quota for a price. It isn’t documented because it varies based on an application-by-application basis.
