How can you guarantee that is human traffic?
Is it adsense safe?
If i buy 10k visitors, how much time is expected to get this traffic?
You will be able to track traffic on your google analytics, Visitors operating systems, countries, even browsers, That should be enough proof for you that traffic is real
Yes it shouldn't have any problems with adsense
We can deliver it in one day or 10 days up to the limit you need, But if it's for site with adsense then i'd recommend to split it over time duration
