There are a lot of bounties that will give you such a reward at the ICO prices. Just find a great signature campaign and write a lot of content for other projects. These are the most profitable campaigns. But the problem is that even if you get 1000 USD at the ICO price, as soon as the token will be live on exchanges, this 1000 turns to 100 USD.
I wrote a lot of content on other project , but in the end many of them are unwilling or unable to go on exchange. Don't know what it involves. But most likely it is due to the fall of the entire industry of crypto. ICO can't find investors for their ideas even if their project inspires confidence.
